I’m adding my voice to this. I ran into this kind of issue while trying to integrate modeltranslation into mezzanine/cartridge. In the end, I have something along the lines of...

In Mezzanine, I use `fields = ()` instead of `pass` whenever there is no (or no more) fields to translate. Can you make the change to see if it helps...

This is a [bug of django-modeltranslation](https://github.com/deschler/django-modeltranslation/issues/315) that never got addressed. One workaround would be to manually add translated fields using `EXTRA_MODEL_FIELDS` for each target language.
