I'm also getting this crash with the latest unity and all updates as of 2012-06-11.
I can force this crash by opening nautilus and pressing Control-N 20 times to open 20 nautilus windows. The next time I press Alt-Tab or Super-W I will get the crash.
By opening 20 nautilus windows I can also crash Gnome-Shell, so I think this is definitly a graphics driver issue :-(.
