Comment 7 for bug 1112871

Hallo Bryce
No I'm not able to reproduce this using totem.
My system never experience this issue before.
Never experienced freeze in Raring developement.
Describing better, initially I've noted the freeze of Unity, but X was working, then after some seconds, Unity and compiz wasn't working (launcher and windows borders disappeared as showed in the attached screenshot).
Also I've noted this in .xsessionerrors:

[mi] EQ overflowing. Additional events will be discarded until existing events are processed.
