Django migrate command fails with foreign key to user model

Question

I have a very simple test application, test_app, in django 1.7b2 that consists of only one model:

models.py

from django.db import models
from django.conf import settings

class TestModel(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL)

When I run python manage.py makemigrations test_app, I get no errors and the migration file is created successfully. However, when I come to run python manage.py migrate, I get the following error:

Operations to perform:
  Synchronize unmigrated apps: admin, contenttypes, auth, sessions
  Apply all migrations: test_app, auth
Synchronizing apps without migrations:
  Creating tables...
  Installing custom SQL...
  Installing indexes...

What I am doing wrong?

This is apparently a known bug and is being tracked in django ticket #22485
