permissions field.

Reporter: chronos |

Milestone: 1.2

-------------------------------------------------------------------------+--
When we create custom permissions for model, works perfectly if we use
like this:
{{{
class Meta:
permissions = (
('can_view_info',"Can view info."),
('can_view_reports',"Can view reports."),
('can_export_reports',"Can export reports."),
('can_search',"Can search."),
)
}}}
But, if we use like that, for multiple language sites:
{{{
class Meta:
permissions = (
('can_view_info',_("Can view info.")),
('can_view_reports',_("Can view reports.")),
('can_export_reports',_("Can export reports.")),
('can_search',_("Can search.")),
)
}}}
We get psycopg2 raising following error on syncdb:

psycopg2.ProgrammingError: can't adapt
}}}
This error happens with Django 1.1 beta 1 and Django 1.2 pre-alpha
(current svn). I tested with psycopg2 versions 2.0.12 and 2.0.13.
This problem probably is similar to SafeString and/or SafeUnicode issues
on #5996.
Soon I'll try to fix this and post more info about problem.
