    27 I think this is caused by the admin thinking that having a foreign key field as a primary key is the same as concrete inheritance. So when you try and check lookups for {{{restaurant__place__country}}} it thinks 'place' is the concrete parent of 'restaurant' and shortcuts it to {{{restaurant__country}}} which isn't in 'list_filter'. And you can't add {{{restaurant__country}}} to list_filter because country isn't actually on restaurant.
