I'm using the nvidia driver.  Switched to the nv driver and things 
aren't the same, but I still occasionally got the same sort of crash (I 
played randomly with various atom selections, then configuring the 
selection).  It seemed harder to force a crash with the nv driver, but 
it's really too little data to say for sure.

For both drivers I find times when the python code somehow freezes up 
as well (mentioned at the end of my post above) which I haven't 
isolated yet.
