Reinstalled to EEEPC-900, then updated and switched to classic desktop. No such crash occurring.

When I enabel compiz and open nautilus file manager it is impossible to move opened window through desktop!
Nautilus can move again when I switch back to metacity window decorater!

[emperor (emperor2000)]

To whoever is experiencing the problem: Just do compiz --replace and it will (temporarly) work again.

seems similar to bug #711231

Happening right after running unity with the --verbose flag (another instance of unity was running, though).
