Invalid argument error on my custom taxonomy

This error: Invalid argument supplied for foreach() in /home/dswp/public_html/userylf/wp-includes/post.php on line 1016 is coming back. When I checked the file it appears something is wrong with my taxonomies. I have no idea what, I’ve rewritten them a hundred times and checked against codex. Perhaps a fresh set of eyes? THanks!!

add_action( 'init', 'create_film_categories' );
function create_film_categories() {

  $labels = array(
    'name' => _x( 'Film Types', 'taxonomy general name' ),
    'singular_name' => _x( 'Film Types', 'taxonomy singular name' ),

    'all_items' => __( 'All Film Types' ),
