Status changed to 'Confirmed' because the bug affects multiple users.

It happens when Nautilus is in the «/media» dir (or subdirs of «/media») for a time (I don't know how long but I think more than one minit) an when I click on «Home» -> Compiz crash.

This seems a duplicated of lp:1161916, feel free to reopen this if it won't be fixed with that.
