Digging into this a bit more, the specific exception is that it is trying to insert a contenttypes row with a null 'name' value.
The code in question is doing a get_or_create() on the contenttype object. I assume it should be picking up the name from the name @property on the ContentType model, but I don't see that ever actually being called.
