Frequent Gnome lock-ups since fresh F18 install

[Digimer]

Hi all,

   I had F17 and updated it last week to F18. It was perfectly stable 
and I had no problems with Gnome.

   I did a fresh install of F18 (fresh drive) on Sunday and since then 
Gnome 3 has locked up hard on me six times (three times just today). 
Each time, I can ctrl+alt+f2 into a terminal and I've tried restarting 
various things without successfully recovering.

   If I run 'init 3' -> 'init 5', Gnome restarts and the system is 
usable again. It seems to happen randomly, though it generally happens 
when I am flipping between windows with alt+tab or alt+tilde. That said, 
it just crashed on me when I tried to unlock the screen after being gone 
for about an hour.

   This time, I checked syslog and these were the last messages before 
the lock up;

===========

Feb 12 21:39:22 lemass dbus-daemon[749]: ** Message: No devices in use, exit
===========

   This time I tried restarting dbus.service and it closed and, 
eventually, restarted Gnome.

   This is getting to the point where I can't really be productive with 
my laptop. Whenever it hangs, I lose anything not yet saved as gnome 
becomes totally unresponsive. I am not sure what I would open a ticket 
on even.

Any help would be appreciated.
