Description

Using an AbstractUser based user model with Django 1.8 RC1 causes the management command to create the database table layout to fail: "python manage.py migrate"

Traceback:

File "manage.py", line 9, in <module>

What happens is that the django_migrations table gets created. Creation of all other tables are discarded/reverted due to this error.

If necessary, I may be able to provide a minimal code for reproducing this issue. It's happening in five independent projects for me. I hope I'm doing something wrong here, but it may just as well be a bug.
