I'm going to take a guess and suggest it could be your post_save signal being registered multiple times as a result of the models.py being loaded more than once.

Try changing the last line to something like:

post_save.connect(create_user_profile, sender=User, 
                    dispatch_uid="user_create_profile")

Having the dispatch uid will cause it only to be registered once, even if its called many times as a result of imports.
