Bug#662639: gnome-shell: frequent lockups on hardware accelerated actions

[Rainer Kupke]

Looks like I am getting this under 3.4.1-7

Sometimes I can switch to another virtual console with ctrl-alt-Fx, login via ssh always works.

Killing gnome-shell rarely works. 

After "kill -9" ps lists the process as <defunct>, but gnome-shell does not come back.

When I reboot/shutdown via ssh the screen stays frozen until the shutdown is complete.

I found a way to trigger the crash:
Create a document in LibreOffice writer, hit return to create a few (4+) pages and use the scrollwheel for a few seconds.
