Bug Description

Gnome-panel will crash with a sigsev fairly regularly for me - usually it is when launching a new window or switching desktops, but it happens within about 20 min of normal use.

In an xterm or console window I can re-launch it from the command line. This means that I have been able to collect core dumps, retrieve the stacktrace from gdb, and collect the system call log by launching it with strace -o.

I could build it from source with debug symbols, or try other experiments if that could help with this.

I have pasted the last bits of an strace log and core dump stack below.

Instead of having to click around and wait for gnome-panel to eventually crash, I now have a repeatable way to crash it immediately, on the first try every time - If I try to launch the Chromium web browser from the Applications -> Internet menu, it crashes immediately.

Robert Ristroph, thank you for reporting this and helping make Ubuntu better. However, your crash report is missing. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer. First, execute at a terminal:
cd /var/crash && sudo rm * ; sudo apt-get update && sudo apt-get -y upgrade && sudo apt-get -y install gnome-panel-dbg && sudo service apport start force_start=1

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

Now reproduce the crash, then open your file manager, navigate to your /var/crash directory and open the crash report you wish to submit.
If this fails you will have to open a terminal and file your report with 'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is the crash you would like to report. If you get an error that you aren't allowed to access this report you will have to file it with 'sudo ubuntu-bug /var/crash/_my_crash_report.crash'. If you run the command against the crash report and a window pops up asking you to report this, but then never opens a new report, you would be affected by https://bugs.launchpad.net/ubuntu/+source/apport/+bug/994921 . In order to WORKAROUND this, one would need to open the following file via a command line:
gksudo gedit /etc/apport/crashdb.conf

and comment out the line:
'problem_types': ['Bug', 'Package'],

by changing it to:
# 'problem_types': ['Bug', 'Package'],

Save, close, and try to file the crash report again via:
ubuntu-bug /var/crash/_my_crash_report.crash

I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently.

Please do not attach your crash report manually to this report and reopen it.

Thank you for your understanding.
