segfault and gnome logout

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

After resuming from suspend, in kern.log I got:
workrave[1484]: segfault at 3f8b8050 ip 034f25f8 sp b6e01f10 error 4 in libc-2.12.1.so[34c3000+157000]

I got the gdm log in screen and found out that gdm restarted and none of my apps' statuses were saved.

+1

We're are also having this problem in a machine.

We're seeing this in connection to a sudden session crash; garbage is shown in screen and after some seconds gdm appears with login prompt.

Hi all. Just confirming the same -- Gnome (X?) crashes, GDM restarts, and then I presented with a login screen.

A runaway "gnome-panel" process drains the CPU and I have to kill it every time.
