-------------------------+-------------------------------------------------
A DataError raises while permissions are created.
I think there is a problem because of the long model names - the
Permission model, while saved, is not validated against the db fields-
mainly:
{{{
name models.CharField(_('name'), max_length=50)
}}}
that is easy to reach.
Traceback:
{{{
