I have seen this crash twice in running my code over 100 times, so it’s pretty
hard to reproduce, but definitely there.
It seems to be related to deallocating an OUIInspectorPane object, but when I
look in the debugger, it is actually my subclass of that object. I have zombies
turned on, but that didn’t seem to isolate the problem.
Can anyone suggest a way of tracking this down?
