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.

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.
