I have been experiencing crashing issues on the fglrx drivers. They are specifically when entering or leaving a clip scene.
They seem to occur less often and less predictably with FastTLS set to 2 (safe-handling). I will try later to instead to set FastTLS completely off to see if that fixes the issue.
If that doesn't fix the issue in the majority of cases I will likely report a bug. Otherwise I will presume the issue is with the AMD Drivers, and file a note in the Tips and Tricks section.
