[SOLVED]Thunar 1.8.0-1 Segfault

akovia · 2018-06-15 12:13:24

Arch Linux fully updated.

Thunar will no longer start after updating a few days back. I had one instance open that was continuing to work, but trying to open a new instance would segfault. I just updated again and rebooted, but can't open thunar.

Thunar[889]: segfault at 8 ip 00007f5227333578 sp 00007ffe48a2cb90 error 4 in libgobject-2.0.so.0.5600.1[7f522731a000+52000]

Downgraded to 1.6.15-1 and it will start again. Funny thing is that it says version 1.8.1 under the help menu in the GUI, but properly lists the version from the terminal.
Maybe I need to downgrade some plugins as well.

$ thunar --version
Thunar 1.6.15 (Xfce 4.12)

I am freaking out a bit without my file manager. Looking for some advice to troubleshoot this further.

Thunar can run in daemon mode:

$ ps -ef | grep -i thunar
toz       4008  3364  0 17:09 pts/1    00:00:00 grep -i thunar
toz      13130     1  0 Jun11 ?        00:01:03 Thunar --daemon

Daemon mode is useful for things like device automounting, but if you upgrade thunar without re-starting the daemon, you'll run into an inconsistent state. Either restart the thuanr daemon or log out and back in again.

Does the problem still exist after the restart or logout/in?

Thanks ToZ, sorry I wasn't clear before. I rebooted and I still couldn't open thunar.

Just tried again.

Starting full system upgrade...
resolving dependencies...
looking for conflicting packages...

Just tried removing both
thunar-dropbox 0.2.1-1 & thunar-megasync 3.6.5.0-1
but still no joy.

The only other thunar related packages I can see are
extra/thunar-archive-plugin 0.4.0-1 (xfce4-goodies) [installed]
extra/thunar-media-tags-plugin 0.3.0-1 (xfce4-goodies) [installed]
extra/thunar-volman 0.8.1-2 (xfce4) [installed]

Downgrading to thunar 1.6.15-1 seems to be working for now.
Not sure what to try next.

Try running thunar through gdb and get a backtrace:

thunar -q
gdb
file /usr/bin/thunar
run

When you get the crash, do:

bt

...it might point out where the problem is from.

Also:

sudo updatedb
locate -i thunar | grep bin

I'm not completely code illiterate, but that backtrace means little to nothing to me, other than the modules that are failing.

ToZ · 2018-06-16 00:41:56

There are no obvious thunar components listed in the backtrace, just gtk3/glib components.

Are you running stock gtk3/glibc/glib2 from the arch repositories? Do you have any non-respository (AUR/ABS) packages installed that are related to gtk3/glib2/glibc?

Does the following return sane values?

ldd /usr/bin/thunar

Maybe also confirm your versions of those packages:

pacman -Qi glibc | grep -A1 Name
pacman -Qi gtk3 | grep -A1 Name
pacman -Qi glib2 | grep -A1 Name

I am running the gtk3 vertex theme listed above. I'll fiddle with that tomorrow evening after work. Hopefully it's that simple.
Seriously appreciate the help here! Will report back.

ToZ · 2018-06-16 02:25:39

Is this result set from Thunar 1.6x? It has gtk2 libraries listed. Thunar 1.8x is gtk3-based.

Can you get the same output for Thunar 1.8.1. If this is from thunar 1.8.1, then it looks like there is an issue with your install files.

akovia · 2018-06-16 10:51:53

Got up early and tried a few different themes but nothing worked.

Is this result set from Thunar 1.6x? It has gtk2 libraries listed. Thunar 1.8x is gtk3-based.
Can you get the same output for Thunar 1.8.1. If this is from thunar 1.8.1, then it looks like there is an issue with your install files.

Hrm. Everything looks okay.

Can you try to get an strace to see if it shows something?

strace -o thunar.strace /usr/bin/thunar

...and post back the contents of the thunar.strace file.

Another thing you could try is to install "thunar-git" from the AUR (this package will be the same as 1.8.1 with only a couple of translation additions). Since you use yaourt, during the process say "Yes" to "Edit PKGBUILD" and make 2 changes:

1. in the prepare() function change "--disable-debug" to "--enable-debug=full"
2. in the build() function, change "make" to "make CFLAGS=-Wno-error"

Once completed, run "thunar -q && thunar" and see if anything interesting gets displayed in the terminal window.

akovia · 2018-06-16 21:10:38

Back again with some good news.
I remembered this problem that I thought might be related to a config file problem so
I decided to back up my .config/Thunar folder to start clean and it opened fine.

Turns out it was in the uca.xml file. The file is huge so it took a while to nail down the bad action.

<action>
	<icon>/home/akovia/bin/FontRename4/FontRename4_48x.png</icon>
	<name>FontRename4</name>
	<unique-id>1449505078303158-7</unique-id>
	<command>xfce4-terminal --tab --drop-down -H -x  java -jar /home/akovia/bin/FontRename4.jar  -h1 -m3 -s %F | tee -a fontrename4.log</command>
	<description>Rename Fonts </description>
	<patterns>*</patterns>
	<directories/>
</action>

I haven't used this action in years so it's no loss, but 1.8 does not like it. I never knew that Thunar parsed the actions on start.

Hopefully this info will be useful to the devs and they can trap problems like this to give some useful error messages. Please let me know if you still want the strace, but I'm hoping you can replicate the problem now.

As always, a serious thanks for helping!!

EDIT:
I just found this. LOL!

Strange. The action file works on my computer. I don't have the fontrename4.jar file though to test if fully. Where can I get a copy?

EDIT:
I just found this. LOL!

We've come full circle, haven't we? There is a good chance that I am to blame for this mess. lol.

akovia · 2018-06-16 22:46:45

Wow, I just can't catch a break!

I zipped up the fontrename4 folder to send it to you. It zipped up just fine, but when I clicked on the archive, thunar crashed again.

Removed my config files again and I'm back in business. *For now*

Here's some dmesg errors:

[Fri Jun 15 17:27:14 2018] thunar[18181]: segfault at 8 ip 00007f5f05748578 sp 00007ffd4c809b70 error 4 in libgobject-2.0.so.0.5600.1[7f5f0572f000+52000]

and from the console:

~ $ thunar
double free or corruption (fasttop)
Aborted (core dumped)

Here's fontrename4

It crashed every time so I should be able to narrow it down again. Will try to find the cuprit after walking the dog.
Was something changed in 1.8 in the way custom actions are handled?

ToZ · 2018-06-17 00:01:03

I'm sorry but I can not replicate this on either of my Arch systems. The custom action with the actual jar file works fine.

Was something changed in 1.8 in the way custom actions are handled?

Alot was changed between 1.6.15 and 1.8.1 - namely the gtk3 and dbus-glib to GDBus migration. A complete list of changes to the UCA plugin are listed here. 1.6.15 was released in about Feb 2017.

Since you got a core dump, see if you can analyse it to determine cause (https://wiki.archlinux.org/index.php/Co … _core_dump).

akovia · 2018-06-17 15:30:15

Well I did find the next problem custom action that allowed me to select that archive, but now I get crashes when selecting other particular files. Some files are just fine, so I think it has to do with accessing metadata from files possibly? Still not sure how that interlocks with custom actions. Here was the last culprit.

<action>
	<icon>terminal</icon>
	<name>Compare</name>
	<unique-id>1449505144320664-10</unique-id>
	<command>xfce4-terminal --tab --drop-down -H -x cmp %F</command>
	<description>Compare files with cmp</description>
	<patterns>*</patterns>
	<audio-files/>
	<image-files/>
	<other-files/>
	<text-files/>
	<video-files/>
</action>

The dmesg error now is this:

traps: Thunar[876] general protection ip:7fb902d135c6 sp:7ffc6f4f3880 error:0 in libc-2.27.so[7fb902c90000+1b3000]

Just poking around google with my error msgs points to a lot of problems with nvidia drivers. My card is a bit old (GeForce GTX 660), but is still supported and I'm using the latest drivers of course. I'm not sure how many packages I'd have to downgrade to go back to an earlier nvidia driver. At least the kernel and vbox drivers I would think.

I just had a problem with not being able to mount my luks drive in thunar out of the blue as well in either version of thunar.
"error storing passphrase in keyring" "the name org.freedesktop.secrets was not provided"
I was able to manually mount it through the terminal, but not thunar. Tracking that down had me install gnome keyring which I removed back in February because it was screwing with chromium.

So I'm not sure wth is going on, but these latest rounds of updates have royally screwed my system up. Not sure if anything is related, but the fact that I can't find others with the same problem makes me think it might just be an nvidia driver problem with my particular card. I am certainly open to more troubleshooting suggestions, but these errors are so general in nature that it's hard to pin down the exact cause.

ToZ · 2018-06-17 16:55:05

If there was some way to replicate this on another system, it would make sense to create a bug report. This last custom action works for me as well, but I don't have an nvidia card.

The real wildcard is that it works with Thunar 1.6x - and the main difference between the two versions is gtk3 and dbus.

Perhaps you could rule out a profile issue. Create another temporary user on your system and test these there. It will help in determining if its a systemic problem.

akovia · 2018-06-17 17:25:16

So I still had a clean profile from troubleshooting this issue.

Everything seems to work fine until I copy over my uca.xml and then the fun starts to happen. Clicking on a jpg file crashes thunar. Here is the corresponding ca that when removed, the crashing stops.

<action>
	<icon>application-pdf</icon>
	<name>JPG to PDF</name>
	<unique-id>1408655656096142-3</unique-id>
	<command>convert -compress jpeg %f cover.pdf</command>
	<description>Concert Image to PDF</description>
	<patterns>*.jpg;*.jpeg</patterns>
	<image-files/>
</action>

At least this ca corresponds to the type of file it filters. The fontrename4 worked on all files which would explain why thunar wouldn't open at all, but the cmp action worked on all files as well and didn't prevent thunar from opening. At least it doesn't appear to be a profile issue.

akovia · 2018-06-19 01:48:14

For anyone ending up here, it appears this will be fixed in 1.8.2
