Comment 31 for bug 307019

When attempting to login to such a locked-out account, one will get the following error dialogs:
Could not update ICEauthority file /home/$USER/.ICEauthority [Close]
There is a problem with the configuration server. (/usr/lib/libgconf2-4/gconf-sanity-check-2 exited with status 256) [Close]
Nautilus could not create the following required folders: /home/$USER/Desktop, /home/$user/.nautilus. Before running Nautilus, please create these folders, or set permissions such that Nautilus can create them [OK]

Once you click on [OK] on the third error message the background graphic will stay but nothing happens. At this point I had to use a console (CTRL ALT F1) to login as the admin user, reset the password and restart GDM (leading to data loss if any other sessions were open).
