Definitely some kind of driver problem, sounds similar to a driver nvidia users have with certain compiz settings. For a workaround you could login to these users with the Failsafe GNOME session and change System->Preferences->Appearance Visual Effects tab to None. After that you should be able to login to these users without having compiz start.
