Does this xserver patch fix the crash?
Yes, the crash no longer occurs with this patch applied. Thanks for looking into it.
Thanks for testing it.
BTW this indicates that the client is using a picture without any defined contents as the source of a Composite operation, which seems pointless at best but might even result in visual corruption - do you notice any?
No, haven't seen any corruption. Is there a way of finding out whats causing this?

Might be tricky... One possibility might be to reproduce the crash while running Firefox with --sync, attaching gdb to Firefox and setting a breakpoint in a strategic place which allows seeing which Xlib call causes the X display connection to drop. But I don't know offhand where that breakpoint could be placed.
Okay, I will try and see if I can come up with some results.
Fix has landed in xserver master.
