It might be in mainline, it just happens once in a couple of days and since I'm not usually fuzzing
mainline I can't say for sure.
I've tried bisecting but since I don't have a reliable way to reproduce it the bisection goes wrong
pretty fast.
I've tried adding some debug code in, which clearly suggests that the object is gone, but I can't
pinpoint to where it disappears.
Thanks,
Sasha
