Bryan:
It could well be incompatibility between the newest xorg and the NVIDIA drivers. As the backtrace includes an NVIDIA driver binary function the folks who are in the best position to answer this are NVIDIA as they will be able to say "yes it's xorg doing something wrong right here" or "it is a bug in our drivers". I doubt the problem lies with Ubuntu's packaging of the NVIDIA drivers because John clearly stated he has tested the binary from the NVIDIA site too (of course I am assuming that John was really running that driver).

To put it bluntly there's no way this can be compiz as compiz is a userland app and thus only "talks" to the X server. This is either a bug in xorg or the NVIDIA binary drivers (or the compiler miscompiling something or the etc) and unless you can tell me what is happening in the the function _nv002196X+0x1f7 along with what was happening in the run up to that function I suspect you will struggle to narrow this down...
