Thunar crashes (segfault) when hiding hidden files

Hi Everybody,

I am currently experiencing problems with thunar (thunar 4.20.7 (Xfce 4.20)) on archlinux: It crashes as soon as I try to make hidden files invisible (again), either using Ctrl + H or the file menu.

The issue seems to be very similar to the one described in the followng thread:
https://forum.xfce.org/viewtopic.php?id=14592

The behavior changes (i.e. does not crash anymore) as soon as I close the "tree view" sidebar. So this is also a valid workaround for me.

On my machine, the problems can be reproduced from a "clean state" (i.e. hidden files invisible, no sidebar) as follows:
1) Open sidebar with tree view (Ctrl + E)
2) Ctrl + H for showing hidden files
3) Ctrl + H for hiding hidden files
-> Crash

Sometimes 2-3 have to be repeated multiple times (up to 4 times) until the crash occurs.

Anyone else experiencing this?

Re: Thunar crashes (segfault) when hiding hidden files

Hello and welcome.

I'm also using Archlinux and thunar 4.20.7 and I can't replicate this problem. How many file are there (including hidden) in the directory you are testing on? Is it a local drive or remote?

Are you able to get a backtrace??

The crash sounds like this bug: https://gitlab.xfce.org/xfce/thunar/-/issues/1460

Re: Thunar crashes (segfault) when hiding hidden files

Yes, this seems to be the issue, thanks for pointing that out.

I checked several different folders - it does not seem to depend on the actual directory, but happen everywhere (even in empty folders). It's a local file system.

gdb's output right after the crash:

Thread 1 "thunar" received signal SIGSEGV, Segmentation fault.
0x00007ffff7130972 in g_node_traverse_pre_order (node=<optimized out>, 
    flags=flags@entry=G_TRAVERSE_ALL, 
    func=func@entry=0x5555555e0f40 <thunar_tree_model_node_traverse_visible>, 
    data=data@entry=0x555555a23590) at ../glib/glib/gnode.c:506
506		  child = current->next;

The full backtrace is really long, is there something particular that you are looking for or do you want me to upload the gdb-stacktrace somewhere?
