This patch should be a good workaround: http://cgit.freedesktop.org/~ickle/mesa/commit/?h=brw-batch&id=e2a696a4cd93c2dbe445243de48ed478fbdb8009
I will test it tonight on my home machine and see if I can reproduce it. The patch may make the screen flicker for a frame instead of crashing. The actual problem is a race condition of DRI2 that is not trivial to fix.
