In Admin "list_filter" does not respect "limit_choices_to"

[david@…]

If a list filter is defined as

    list_filter = ('nl_group')

And the 'nl_group' field is defined as

  nl_group = models.ForeignKey('self', limit_choices_to = {'o1type__exact': 'NL'}, null=True, blank=True)

Then the list filter will show ALL distinct values of 'self' rather than the distinct values in 'self' that have oltype='NL'
