While troubleshooting a different problem, I swapped my GPU to an older card
that I had and noticed mythtv segfaulting as well.  I think it is a GLX
problem as glxgears segfaulted too.  I was using the same kernel as you (
2.6.18-1.2849.fc6) and a GeForce 4200 Ti.  I didn't really investigate it
too much because switching back to my newer GPU solved this, but it seems
something may have changed in the recent kernel/nvidia driver/nvidia kernel
module to cause this.  Verify that glxgears segfaults as well and then try
rolling back.  Post your results--I had been fearing something was broken
with my old GPU.
