Comment 1 for bug 1528710

This does appear to be a regression.

This is a change that only took effect in Django 1.8, if I understand correctly.

There's a related ticket <https://code.djangoproject.com/ticket/25452#comment:2> and I had a brief discussion about this on #django-dev; please do feel free to file a ticket against upstream and a patch can probably be backported. I'd prefer to see it fixed in Django upstream first, though.
