gnome-panel workspace switcher segfaults when switching workspaces

[hype]

Binary package hint: gnome-panel

Using Hardy Heron, up to date (03/17/08)

I noticed gnome-panel crashed often when using the workspace switcher applet, especially if i have amule running.
I generated a gdb log (but couldnt find any info specific to the fact that amule is running)

I noticed a similar bug, https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/89471, but this one seems to be reported to Edgy Eft.

ii gnome-panel 1:2.22.0-0ubuntu2

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a ".crash" file. Please follow these instuctions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

If you are using Ubuntu with the Gnome desktop environment - launch nautilus and navigate to your /var/crash directory and double click on the crash report you wish to submit.

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. Thanks in advance for your cooperation and understanding.

ok, found nothing revelant in /var/crash: no bug concerning gnome-panel.
I did run gdb, attach gnome-panel's pid, and created this gdb output. So there's nothing more i can do.
Thanks for "help".

the trace you submitted doesn't show any symbol just a kernel_syscall that isn't useful at all, please look at http://live.gnome.org/GettingTraces/Details to see how a good backtrace looks like, thanks in advance.

Ok, thanks for help.
I installed gdb package related to libgtk, here is the new gdb output, which seems more understandable. (see attached file)

To sum-up:

Program received signal SIGSEGV, Segmentation fault.

rock on, thanks for doing it, it indeed contains some symbols but not all of them, please follow this instructions in order to get a more detailed stacktrace: https://wiki.ubuntu.com/Backtrace , thanks in advance.

Thats precisely the link i followed to provide this backtrace.
I actually used the second part:
"Already running programs"
on this exact same wiki page.
(as gnome-panel is set to restart, it's more handy to attach gnome-panel's pid than running it from gdb)

Also, i didnt only install libgtk-gdb, but gnome-panel-gdb.
Thought it would be fine to track a bug in gnome-panel.

Wow, seems i forgot 30% of the back-trace info. (after the "continue" :p)

I added libglib2.0-0-gdb; here is the hopefully complete crashlog (attached file)
