Comment:
I've attached a patch that resolves the issue. Included are updated tests
that check for the following:
Child1 is a subclass of both Parent1 and Parent2;
Parent1.objects.select_related('child1') should not throw an error (see
traceback in comment:10).
Child2 is a subclass of Parent1 and has a OneToOneField to Parent2; doing
Parent2.objects.select_related('child2') should not throw an error (same
traceback).
