I am having problems with Gnome 3 on Fedora 15. It has nothing to do
with Mythtv. Xclock, xmms, etc. will cause the Xserver to segfault every
time. The virtualbox gui console causes the problem as well. The system
gets kicked back to a login screen. Surprisingly, starting the
virtualbox VM via the command line runs just fine. I've had an audio
file within Firefox cause the problem but I believe it was using xmms.
The problem was every time Firefox started it went off to restart that
tab causing the segfault. Firefox safe mode had to be used to break that

The drivers are coming from atrpms but the binary ones that get compiled
will do the same thing. The video card is integrated into the
motherboard and is - VGA compatible controller: nVidia Corporation C61
[GeForce 6100 nForce 400] (rev a2).

Fallback mode can be forced by starting System Info, select Graphics and
set Forced Fallback Mode On. The segfaults don't seem to happen in
Forced Fallback Mode.

Mythtv actually runs fine and recordings and live tv play okay without
causing the xserver segfault.
