I think I had the same issue and got it fixed by installing
xf86-video-ati, drm and mesa from xorg git yesterday. Here most times
(but explicit not always) the complete X session got killed with a
segfault (in random places, sometimes xorg, sometimes
xfce4-session, ...) when I tried to switch between compiz and metacity
or xfwm4.
Right now I don't know if the driver, drm or mesa was at fault, but I
*think* it is mesa.

I have an ati rv530 on Debian sid, mesa / dri 7.4.1, and using the stuff
from git fixed the issue (at least up to now no re-occurrences).
