When you write a faulty getattribute that returns None instead of raising AttributeError, it's not realistic to expect getattribute to be in the stack trace.

PyChecker might want to give an error if flow in getattr[ibute] doesn't either pass through a return or a 'raise AttributeError'. Even if the intent is to have attributes default to None, an explicit 'return None' could be added.
