Bug Description
I was trying to test the guest session with Unity enabled. I have a ATI HD5470 graphics board. While logged in the guest session, Compiz and Unity would not behave properly (basically the unity overlay does look like black rectangles overlaid on top of the windows, quite randomly, not unlike the infamous old "black windows bug").
When I tried to disable the Unity plugin, Compiz and the guest session as a whole crashed.
