UI locks up when resuming laptop from sleep. Killing mutter helps.

[Tor Klingberg]

Binary package hint: mutter

Sometimes when I resume my laptop from sleep, the user interface is locked up. I use netbook remix 10.10. I can move the mouse, and the cursor changes depending on what it hovers over, but clicking anywhere has no effect (on application or the Gnome/Unity bars).

If I switch to a console (Ctrl+Alt+F3) and open htop, I see the process mutter using 100% cpu. If I kill the mutter process, the system works again. I see the system bars restarting.

The file apport.mutter.KrygvY.apport attached was made from the console before killing mutter.
