On Django 1.8, I'm encountering this error when attempting to apply migrations
on the production system. What's interesting is that it works fine on the dev
system, and inspecting the django_migrations table, I don't see any
(meaningful) differences between them (error text below).
There was a model added to the "catalog" application which is not being created
in django_content_type.
Manually migrating contenttypes individually generates the same error.

$ python manage.py migrate
