I'm having a little trouble integrating a zinnia app into my current
application.
(project)username@computername:~/project/application$ python manage.py migrate
Operations to perform:
Synchronize unmigrated apps: bootstrap3
Apply all migrations: project, activity, zinnia, sessions, auth, badge,
admin, coupon, contenttypes, sites
Synchronizing apps without migrations:
Creating tables...
Installing custom SQL...
Installing indexes...
Running migrations: Applying zinnia.0001_initial...Traceback (most recent call

This can happen if you are inheriting models from an app with migrations (e.g.
contrib.auth)
in an app with no migrations; see
https://docs.djangoproject.com/en/1.7/topics/migrations/#dependencies for more
I'm using python 3.4.0 django 1.7.5 and latest versions of zinnia (0.15.1).
This is the output of my pip freeze: (as I said, its an existing app so I
have other packages installed for it)

I have a feeling this has to do with a model I have in my application which
has from django.contrib.auth.models import AbstractBaseUser,
PermissionsMixin, UserManager But I can't imagine not using that in my app.
Maybe it's time to look for another blog package.
Mi environment seems ok because I install zinnia on a empty app locally,
and it works fine.
I've created a stackoverflow question to ask for help, in case you'd rather
