Bug#614019: /usr/lib/gdm3/gdm-simple-slave: Greeter crashes, gdm restarts it, forever

Package: gdm3
Version: 2.30.5-6
Severity: important
File: /usr/lib/gdm3/gdm-simple-slave

When I start up my (virtualbox virtual) machine, GDM's greeter crashes.
GDM restarts it, but it crashes again. GDM never stops trying to restart
it though--I have to SSH in, stop GDM, then run startx to get into X.

GDM seems to truncate :0-slave.log a lot--but I was able to get the
following by tailing the file:
