Binary package hint: xserver-xorg-video-ati

Not sure if Unity/Compiz is pushing the driver to its limits or whether Mumble is doing something really bad.
But i got this crasher twice today, when using the 3 of those components together. I don't have a reproducible way of triggering the crash though.

Here is what I found in the logs:
