Observation info was leaked, and may even become mistakenly attached to some other object. Set a breakpoint on NSKVODeallocateBreak to stop here in the debugger. Here's the current observation info: <all my observers>

This sounds off… you're deregistering obeservers in your observee's
-dealloc? It sounds like object A has observed object B, and object B
is being dealloced, which is removing its observation on object C, but
the framework is complaining about object A.
