I don't think this is a memory management issue; it's come up before 
on the list:

Based on other posts, I don't think there's a general solution, other 
than to avoid doing this sort of cleanup in -dealloc.  I remove/add 
observers in viewWillMoveToSuperview for NSView subclasses (which it 
looks like you might have?).
