Unfortunately this prevents me from combining several proxy subclasses of the same model. In my particular use case, I have two different apps that provide two different proxies of the standard User model. To successfully use both apps I need to create another subclass that combines the two, e.g: {{{ class MyUser(App1User,App2User): class Meta: proxy = True }}} This gives a TypeError: ""Proxy model 'MyUser' has more than one non-abstract model base class"". But since App1User and App2User proxy the same underlying model, there's no ambiguity introduced by this multiple inheritance and I think it should be permitted. Attached is a simple patch to make this work, by permitting additional concrete base classes if they are identical to the one that was already found.
