Comment 20 for bug 711571

I have the same problem on one of my computers, which has a Radeon 4650 running the open source radeon drivers. It is intermittent, though, and sometimes doesn't crash. I have yet to see this crash on my other computer, which has a NVidia 460 GTX with the proprietary drivers. (though since I've heard that NVidia replaces part of XOrg with their drivers, I suppose that isn't too surprising that the behavior is different...)
