New description:

 To reproduce:

 {{{
 add_action('init', 'test_admin_notices', 11);
 function test_admin_notices() {
     global $wp_taxonomies;
     print_r( wp_filter_object_list( array_values( $wp_taxonomies ), array(
 'object_type' => array( 'post' ) ), 'and', 'object_type' ) );
 }
 }}}

 This is because array_intersect_assoc() does a strict comparison:
 {{{(string) $elem1 === (string) $elem2}}}

 Using a manual loop fixes the problem.
