Thanks for your bug report. Could you try to get a valgrind log for the crash (you can follow the instructions on https://wiki.ubuntu.com/Valgrind)? The crash is similar to http://bugzilla.gnome.org/show_bug.cgi?id=475065

[Nick Glynn (exosyst)]

I don't think attaching valgrind would work. I'm none too aware of why and when it happens. It's quite random. If you can document exactly what i need to change to plug it into valgrind then I can make sure that any future crashes are caught correctly.

Thanks, Nick.

[Sebastien Bacher (seb128)]

you can use "gnome-session-remove gnome-panel" and then run it under valgrind

Upstream bug was marked as a duplicate so I have reassigned it to the right upstream bug.
