Hi monnks

I'm trying to use populate to fill three tables at once, and getting invalid SQL. With two tables this works, but with three tables there's a missing IN. By adding some debug code to DBIx::Class::Storage::DBI I was able output the SQL, and this is what is being sent to _prepare_sth:

INSERT INTO scenes ( film, time, title) 
VALUES ( (SELECT me.title FROM movies me 
WHERE ( ( director (SELECT me.name FROM directors me 

WHERE ( name = ? )) AND title = ? ) )), ?, ? )

That looks like it should work if there were only an IN between the WHERE and director. Below is the perl I'm using to demonstrate the problem. Is this a known DBIC limitation, or am I creating the relations in the schema incorrectly? 
package TestDB::Scene {
    use parent 'DBIx::Class::Core';

    __PACKAGE__->table('scenes');
    __PACKAGE__->add_columns(qw<title time description film>);
    __PACKAGE__->set_primary_key(qw<time>);
};

package TestDB::Film {
    use parent 'DBIx::Class::Core';

    __PACKAGE__->table('movies');
    __PACKAGE__->add_columns(qw<title director>);
    __PACKAGE__->set_primary_key(qw<title>);
    __PACKAGE__->has_many( scenes => 'Scene' );
};

package TestDB::Director {
    use parent 'DBIx::Class::Core';

    __PACKAGE__->table('directors');
    __PACKAGE__->add_columns(qw<name>);
    __PACKAGE__->set_primary_key(qw<name>);

    __PACKAGE__->has_many( nasties => 'Film' );
};

package TestDB {
    use parent 'DBIx::Class::Schema';
    __PACKAGE__->load_classes(qw<Film Director Scene>);
};

package main {
    use Modern::Perl;

    main: {
        my $schema = deploy_new_to_temp_file();

        my $rs         = $schema->resultset('Director');
        my @population = (
            {
                name    => "Lesly Tack",
                nasties => [
                    {
                        title  => 'Alligator',
                        scenes => [
                            {
                                title => '1st swamp pan',
                                time  => '05:36-12:01',
                            },
                        ]
                    }
                ]
            }
        );
        $rs->populate( \@population );
    }

    sub deploy_new_to_temp_file {
        my $schema = TestDB->connect('dbi:SQLite:dbname=test');
        $schema->deploy( { add_drop_table => 1 } );
        return $schema;
    }
};
