Get Object Members expects objects to be publically avaliable
Due to some hackory in Django 1.0.2 they overrider get to ensure an instance of the class exists and if not it throws an error.
Which means autodoc can't parse some django modules (ones that use contenttypes and generic relations)
(This is fixed in Django trunk but in the meantime any 1.0.2 (and below) users are stuck)
Will try to attach a patch
