Bug#673211: gnome-shell segfaulting

[Daniel Leidert]

Hi there,

I have the same issue. It began with yesterdays upgrade. Log attached.

There were some hints in .xsession-error, which were related to the
(status-?)bar and probably only the result of the gnome-shell failure.
Unfortunately I don't have them anymore. But the segfaults were reported
in my syslog too:

How can this be debugged? Is there any possibility to create a
backtrace? Where are the debugging symbols then - or do I need to
rebuild gnome-shell without stripping them?
