While poking around with this again, I noticed that the thing causing the error for me was a datamigration (being applied due to it being run in tests) which is (I believe) why I was seeing the issue when trying to run tests but not otherwise. I was trying to grab a contenttype using ContentType.objects.get_for_model(MODEL). So my current belief is that no ContentType was created for that MODEL before that datamigration was run, thus causing it to fail the creation causing the error. Hope that helps.
