nm-applet crashed with SIGSEGV in g_main_context_dispatch()

[Daniel Hahler]

failsafeXServer from xdiagnose kicked in, although my window manager (awesomeWM through gnome-session) was still running.

This crash happened in this context then maybe, when chosing "login to graphical console" in the failsafeXServer dialog killed the session.
