I can reproduce the issue being reported and the provided patch does seem to fix the problem.

I left a few comments on the pull request. Once those are fixed I think this should be good to go.

Thanks. I fixed against your comments. Also, since bulk creation is disabled for inherited models, local_concrete_fields vs. concrete_fields may not matter too much, but I've changed. Thanks again for the fast review!
