Stacktrace shows a kernel stacktrace in firegl_takedown.
You mention you have the latest proprietary drivers installed, yet
jockey does not show either supported fglrx driver enabled:
JockeyStatus:
xorg:fglrx_updates - ATI/AMD proprietary FGLRX graphics driver (post-release
updates) (Proprietary, Disabled, Not in use)
xorg:fglrx - ATI/AMD proprietary FGLRX graphics driver (Proprietary, Disabled,
Not in use)
What version of fglrx do you have installed exactly?
Have you tried purging fglrx completely, and reinstalling from jockey?
