   ... do stuff

Inheritance will follow ModelForm up the chain until it hits BaseForm and then stop following up further, but ModelFormMixin is in the __mro__ after the __mro__ of ModelForm and so will never looked at. Just adding a super(BaseForm, self).__init__(.....) to the BaseForm __init__ will work wonders there ...
