With the latest master (`0247c9b08f8da4a2d93b9cede6c615011552b55a`), I'm
getting the following exception:
{{{

I created a sample project to demonstrate the bug:
https://bitbucket.org/berkerpeksag/django-bug You can see the full output
of `./manage.py migrate` at https://bitbucket.org/berkerpeksag/django-
bug/src/b527f36d15c4e68168621dd39db164a8beaf905e/tdj/log.txt?at=master&fileviewer
=file-view-default
The project is simple. I only created a model:
https://bitbucket.org/berkerpeksag/django-
bug/src/b527f36d15c4e68168621dd39db164a8beaf905e/tdj/polls/models.py?at=master&fileviewer
=file-view-default
I believe the cause of the issue is at
https://github.com/django/django/commit/0d3c616fbb2f49fa7ff6809e5a6777275352b35b
#diff-e835ddfb52774b39749788a0d046e477R62 If I replace line 62 with
{{{
issues.extend(super(Command, self)._run_checks(**kwargs))
}}}
it works as expected.
