I'm using django-transmeta to create fields for many langs
Say i have a field "description" and with the metaclass provided by django-transmeta, this field is transformed in description_fr + description_en and so on.
But with commit #12977, it doesn't work anymore, as the work is done by copying field (in the
__new__ method of the Transmeta metaclass), and at this stage, fields have not models and then
__setstate__ (in db/models/fields/__init__.py) fails (because of self.model)
No idea how to make a clean copy of the field without copy.copy...
