This is a general problem with KVO when observing self. As I understand, Apple has recognised the issue though and for apps linked or run on Leopard (one of the 2) the system should be intelligent enough to not print warnings. The best alternative I can suggest is to override -release so that you can sneak some kind of -willDealloc method in before the actual de-allocation and subsequent warnings.

But see, that's the thing. My objects dealloc method fires AFTER the warning appears, so my object hasn't actually been deallocated yet.

In the deallocation my object removes the observers from itself. If my object was actually deallocating first, I should be getting this message.

I'll do some poking around, but I don't think this is a memory management issue. Wouldn't be the first time I've had to eat my words though. :p

See stack frame #2?  You should immediately have recognized that you
have a memory management issue on your hands.  You're failing to
retain the object somewhere.
