22848	Admin initial migration can't find AUTH_USER_MODEL when running makemigrations for the first time	Vidir Valberg Gudmundsson	nobody	"Defining a custom user model (in app 'testapp' and with settings.AUTH_USER_MODEL = 'testapp.CustomUser'):

{{{
from django.db import models
from django.contrib.auth.models import AbstractUser

class CustomUser(AbstractUser):
    foo = models.CharField(max_length=255)
}}}

And trying to make an initial migration, results in an error:
