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
