I can't seem to run the X server from gdb directly - there are actually two
issues. One is if that when I start X from within gdb, it never starts - it
locks up. The second issue is that starting X directly from the command line
doesn't reproduce the crash - it only happens when started by a gnome-session.

Attaching to the process, I find:
