Just to follow up: I've mostly isolated the problem.

It seems that qimage.fill() crashes in the renderthread.

It seems likely we have some sse2 alignment issues. The fact that this happens
in a 2nd thread, and that qt_memfill32_sse2  has some alignment constraints
is probably not coincidental.

I have some work-around in place, and I'm making progress on actually fixing
the issue.
