That particular function is trying to CFRetain the result of -identifier on your store. If you've overridden it, make sure it never returns nil and it always returns the same UUID at least until someone calls -setIdentifier. The UUID should also be set in the store's metadata with the key NSStoreUUIDKey. If you're not preserving the store metadata, including any keys Core Data might set, then you'll have these kinds of problems.
