Having built a debug server it shows that the last checkin to
swrast/s_context.c which adds a _mesa_pb_flush(ctx); call to
_swrast_render_finish() is causing the trouble.
PB->count is greater than 0, but the WriteRGBAPixels() function hasn't
been set and causes the crash. I suspect we need to check ctx->NewState
somewhere and update the state.
Here's the backtrace Brian...
I suspect the DRI drivers could well be hitting a similar problem.
