When you see notifications being sent to random objects, it usually means the original registered observer object was deallocated without removing the observer for the notification. The notification is then sent to a random object that now resides in the reused space formerly occupied by the original observer. I would check if you're removing your observers first before getting too crazy with debugging.

I turned on NSZombieEnabled and a bunch of other settings for my debug session but when I turn on NSZombieEnabled, the crash doesn't occur and the app keeps running.
