gnome-shell crashed with signal 5 in g_log_default_handler()

[Scott Lewin]

I received this error message on logging into cinnamon. This error message popped up with out me doing anything other than logging in. I do not know if it is related, but before logging in with cinnamon I logged in with openbox which was having problems itself.
