Comment 13 for bug 974041

The bug is alive, no changes. Upgrading the X server and intel video driver from xorg-edgers removes the issue. However, now the intel driver from xorg-edgers is based on SNA acceleration, which is still buggy, so it is no longer a good solution.
After upgrade the intel driver from x-updates (to version 2.19) the crashes do not happen, but in place of the crash the screen starts to blink crazily, showing various screen images that no longer exist.

I believe the issue is caused by the bug
bugs.freedesktop.org/show_bug.cgi?id=43146
which was fixed in X server 1.12.
That is why upgrading X to 1.12 always solved the problem.
