Comment (by skyjur):
I have added another test case showing that in 1.9 it's impossible to
extend from abstract models if they contain foreign keys to abstract model
that is not inside an installed app.
In 1.8 this was possible:
https://github.com/skyjur/django-ticketing/tree/master/ticket_26186_2
tox output:
{{{
