ContentType.objects.delete() fails for use since 1.3 (on_delete support to be exact) since it tries to delete all related objects pointing to that contenttype. If one of the related models is not in INSTALLED_APPS (in our case django.contrib.auth), this can fail if the model got imported (which registers it etc…; in our case django.contrib.contenttypes.generic imported auth.models -- via contrib.admin). Attached is a testcase showcasing the issue.
