Comment:

 Could you check if you can reproduce with Django 1.9? It might be resolved
 by the [https://docs.djangoproject.com/en/stable/releases/1.9/#related-
 set-direct-assignment related set direct assignment] change.

 If it's fixed in 1.9, I'm not sure if there's much value in patching
 Django 1.8 as I assume this isn't a new issue and I'm not sure if it'd be
 feasible to fix it without an invasive patch.
