Version: 2.30.1

What were you doing when the application crashed?
Been having problems with GDM (hung in login screen, can see computer icon but no login prompt, thus cannot log in) since applying the latest updates (included firefox, chrome, and dbus) a couple of days ago. This particular crash report happened everytime in the following scenario:
- Startup in safe mode
- From root prompt fire up startx (this is the only way to get to a desktop, besides RDP in of course)
- When the desktop is rendered, this crash report invariably popped up
