Plug-in "Applications Menu" crashes since upgrade

oliver_stotz · 2020-12-31 15:31:04

Hi, i recently upgraded to "Debian GNU/Linux bullseye/sid", and also to version 4.16 of xfce4

As of now, everything seems to be ok, but the panel plugin "Applications Menu" keeps constantly crashing when i try to load it. The eroor i get is a window saying: "Plug-in "Applications Menu" unexpectedly left the panel, do you want to restart it?", which of course doesn't help.

According to a related post here (can't find it ATM), i ran the panel in debug mode

$ PANEL_DEBUG=1 xfce4-panel

and tried to load the plugin from there. here's the console output (sorry, it's long):

=====================================================

========================================================

so, the main problem seems to be "/usr/lib/x86_64-linux-gnu/xfce4/panel/plugins/libapplicationsmenu.so",
which xfce4 either can't find or can't load.

any hints or similar experiences in this regard ?

BTW: the applications menu is there and working when i right-click into the desktop !

best

Interesting.
I just posted similar, can you right click into the 'edit launcher' dialog from the regular desktop menu?

And here in i386 sid the plugin was working fine before I removed it. I will load it again on some round and check again with default and custom menu's. I will check in an amd64 image also, when I get there...

@oliver_stotz,

(xfce4-panel:3056): xfce4-panel-CRITICAL **: 16:20:54.814: Failed to load module "/usr/lib/x86_64-linux-gnu/xfce4/panel/plugins/libapplicationsmenu.so": libgarcon-gtk2-1.so.0: cannot open shared object file: No such file or directory.

Something is wrong here. The 4.16 version of libapplicationsmenu.so should require libgarcon-gtk3-1.so.0., not the gtk2 variant.

Have you logged out and back in again after the upgrade?

What does the following return:

xfce4-panel -V
locate libapplicationsmenu.so
ldd $(locate libapplicationsmenu.so | grep garcon)

I'll note here I'm finding similar weirdness.

For amd64 bullseye/sid xfce4-panel -V

xfce4-panel 4.14.4 (Xfce 4.16)

locate libapplications.so returns nothing...doesn't exist, and did updatedb

garcon is version 0.8.0-1
libgarcon-gtk3-1-0 is installed.

Sorry my bad, it should be:

locate libapplicationsmenu.so

(I'll edit my post above)

xfce4-panel 4.14.4 (Xfce 4.16)

This doesn't look right. It should be xfce4-panel 4.16.0. xfce4-panel 4.14.x is not Xfce 4.16.

Let me throw together a bullseye/sid VM and have a closer look.

amd64/i686/i386 all same situation, however 'Applications Menu' is stable in my examples

Just installed debian stable, updated to unstable and applications menu works. xfce4-panel version is being reported as:

xfce4-panel 4.16.0 (Xfce 4.16)

How did you update?

CwF · 2021-01-02 18:01:02

Updated today, to-be Bullseye now has 4.16.

I said bullseye/sid following the OP mention of the same, that's wrong! It's bullseye/testing still at 4.14.

There is no bullseye/sid now, technically.

Most of bullseye testing is 4.16 with a few as reported above, some form of 4.14.x
...yes, careful with the names! version files are not updated, 'bullseye/sid' is in still showing but will be changed soon. I think the OP is on 'bullseye' currently at 'testing' level, not sid.
