[Bug 40923] GNOME panel crash/segfault on logout

[Sitsofe Wheeler]

Public bug reported:

Affects: gnome-panel (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
Description of the problem:
I recently enabled core dumps on my system after trying to track down a gedit crash on logout. After some testing it appears that gedit isn't the only program that segfaults during a GNOME logout (although it is the one which does it 100% of the time).

Steps to reproduce:
1. Create a ~/.gnomerc file that contains the following:
ulimit -c unlimited
export GNOME_DISABLE_CRASH_DIALOG=1
2. Run
echo /tmp/core.%e-%p > /proc/sys/kernel/core_pattern
3. If you are logged into GNOME logout and then back in again.
4. Run the two scripts
start-internetsoundvideoapps.sh
start-accessoriesgamesapps.sh
waiting for the first script to finish before running the second.
5. After all apps have loaded play a video in totem and some music in rhythmbox.
6. Click the logout button at the top right hand corner of the screen.
7. Click the log out button in the window that appears.
8. Once logout has finally finished switch to VT1, log in and inspect /tmp/ for core files.

Expected results:
No core files to be found.

Actual results:
Following core files were found:
core.deskbar-applet-4465
core.evolution-alarm-5446
core.evolution-excha-4482
core.gedit-5520
core.gnome-panel-4402
core.python-4684
core.rhythmbox-4683
core.sound-juicer-4685
core.totem-4682

gnome-panel stack trace and scripts to come.
