gdm-session-worker crashed with signal 7 in g_simple_async_result_complete()

[Jeremy Bícha]

This happened when logging out of Unity. I think I actually experienced this multiple times in a row as I logged out of Unity several times to test some thing but I also get gdm to freeze up some times when logging out of GNOME Shell.
