I have custom field type. It's a uuid. If I make an inline form in admin interface with a model that has this custom field as a primary key I can't delete it from the admin interface. I get an error that a NoneType doesn't have some attributes.
The problem is that in _construct_form the primary key is got via get_db_prep_lookup which will always return a string. But in _existing_object when it initializes self._object_dict is just takes an object. Which must not be of a string type.
Patch to eliminate it is attached.
