Sorry for dropping the ball on this. I'm afraid it's hard to debug even with this information. If you could run the vm under valgrind (you need to have a valgrind that has randomization disabled - see http://spice-space.org/wiki/index.php?title=Valgrind) it would perhaps point to the culprit. Stack trace would help too, but it won't point to the problem assuming it is memory corruption.
