[issue15193] Exception AttributeError: "'NoneType' object has no attribute

The exception you report looks incomplete:  there should be something after the 'no attribute' saying which attribute lookup failed.

In any case, I don't thing this is a bug.  It sounds like a result of the unpredictability of cleanup order at interpreter shutdown:  you're encountering a situation where the 'Person' reference has already been deleted from the module namespace before the __del__ method for one of the Person instances gets called;  so the 'Person' name lookup in the __del__ method fails.  You could get around this by replacing 'Person' with 'type(self)' in __del__.
