Serious application error. Exception was caught during Core Data change processing. This is usually a bug within an observer of NSManagedObjectContextObjectsDidChangeNotification. Can't use in/contains operator with collection 0 (not a collection) with userInfo (null)
Detected an attempt to call a symbol in system libraries that is not present on the iPhone:
_Unwind_Resume called from function -[NSManagedObjectContext(_NSInternalChangeProcessing) _processRecentChanges:] in image CoreData
