compiz crashed with SIGSEGV in GridScreen::handleEvent()

[Jeroen T. Vermeulen]

This happens when I try to drag a window. The upgrade to Quantal broke Unity completely; the ability to drag windows is the only remaining functionality left that seems to go beyond basic X, but then this crash happens. I suspect it's because Compiz doesn't support my hardware (a mid-2009 MacBook Pro).
