[apport] gnome-panel crashed with SIGSEGV in __pthread_mutex_unlock_usercnt()

Binary package hint: gnome-panel

Can't understand how it happened and when, but it happened... Hope the crash report is useful enough.

Thank you for your bug. Upstream bug similar to that one: http://bugzilla.gnome.org/show_bug.cgi?id=399329

The backtrace is similar, the upstream one is a hang, not a crash though

Debug backtrace:
