Proxy of User model fails on admin interface

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I'm using this class:

    class OrderedUser(User):
        def __unicode__(self):
            return self.get_full_name()

        class Meta:
            proxy = True
            ordering = ["first_name", "last_name",]

2. The admin interface fails with "[42S22] [FreeTDS][SQL Server]Invalid column 
name 
'ordereduser_id'. (207) (SQLPrepare)" when I try to save a new instance that 
has a OrderedUser 
field.

What version of the product are you using? On what operating system?
Django 1.2.1, Django PyODBC rev.182, SQL Server 2005 SP3

Please provide any additional information below.

Please close this issue. It was a problem between the chair and the keyboard.

By creating a proxied field and having a many to many relationship in one of my 
objects - the underlying db 
column changed in the relationship model and my database table was not 
reflecting that.
