Validation doesn't detect import errors

[Afief]

I have a model with a bug in it(I imported user instead of User from django.contrib.auth.models), here is the code:

from django.db import models
from django.contrib.auth.models import user

class myprofile(models.Model):
    user = models.ForeignKey(user, unique=True)

When running manage.py validate I get no errors, but when asking for the app's sql I am told that I probably didn't install it. What should happen is that the model shouldn't validate(or at least be told that the app is found but contains errors)

$ python manage.py validate
0 errors found

$ python manage.py sql myprofile
Error: App with label myprofile could not be found. Are you sure your INSTALLED_APPS setting is correct?
