Have no idea what is going on here, but it seems related to this bug report:

https://code.djangoproject.com/ticket/22280

To reproduce this bug it is enough to add this line:

    from manoseimas.compatibility_test.models import TestGroup

to `manoseimas/compatibility_test/admin.py`, some how it conflicts with `nose`,
but I'm not sure what `nose` has to do with Django apps and models?

Anyway changing the way how `TestGroup` is imported fixes the bug.
