24477	Error Outputting System Checks in django/core/management/base.py	David Muller	nobody	"I'm trying to install celery==3.1.17 with django 1.8b2 (following the [http://celery.readthedocs.org/en/latest/django/first-steps-with-django.html#starting-the-worker-process celery + django install instructions)].  

I get the following TypeError when I try to launch a celery worker AND have unresolved system warnings:

Trying to launch celery worker...
{{{
celery -A my_project worker -l info
}}}

yields ...

{{{
  File ""/usr/local/etc/virtualenvs/gears/local/lib/python2.7/site-packages/celery/fixups/django.py"", line 162, in validate_models
    cmd.check()
  File ""/usr/local/etc/virtualenvs/gears/local/lib/python2.7/site-packages/django/core/management/base.py"", line 530, in check

}}}

It appears that Django is throwing a TypeError at [https://github.com/django/django/blob/stable/1.8.x/django/core/management/base.py#L530 this line in django/core/management/base.py]

The problem ""goes away"" if I silence Django's system checks.
