Disabling some Frabjous apps leads to errors

What happens:
If some Frabjous apps are disabled, you see a DoesNotExist error for ContentType when hitting /admin (see attachment for a traceback).

The installed apps in this case are:
 'django.contrib.auth',
 'django.contrib.admin',
 'django.contrib.admindocs',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.sites',
 'django.contrib.flatpages',
 'django_openidconsumer',
 'frabjous.categories',
 'frabjous.licensing',
 'frabjous.media',
 'frabjous.links'

What should happen:
It should be possible to pick only the bits of Frabjous that you need.
