So. I don't think it has anything to do with pulseaudio, since it hangs and the window greys out even with sound completely disabled.
I haven't gotten it to completely lock up though, so it could be that it only actually crashes if it is trying to play sounds when it locks.
As for Tha's AI theory - maybe? But it probably means someone really screwed up something that worked great in 11.10 - perhaps related to adding that annoying top message area that makes the game area resize.
