Description

Sometimes I get errors like this:

RuntimeError: Conflicting 'event_deferred_description_description_en_descriae804c3400b52ecb4181ed6574468538' models in application 'ticket': <class 'ticket.models.event.Event_Deferred_description_description_en_descriae804c3400b52ecb4181ed6574468538'> and <class 'ticket.models.event.Event_Deferred_description_description_en_descriae804c3400b52ecb4181ed6574468538'>.

or this:

RuntimeError: Conflicting 'event_deferred_description' models in application 'ticket': <class 'ticket.models.event.Event_Deferred_description'> and <class 'ticket.models.event.Event_Deferred_description'>.

It has appeared after migrating to django 1.7.
Where and how I can find reason to fix this mistake?

It looks like this is a problem with the modeltranslation package which does some sort of dynamic model generation. Django never officially supported that and now I think it's forbidden. Does that package claim compatibility with Django 1.7? I don't think this is a bug in Django, please see TicketClosingReasons/UseSupportChannels and reopen with further details if you believe otherwise.
