Remove Media > Categories submenu item

For future reference. You can remove the Media > Categories submenu item with the following function in your functions.php:

function remove_media_categories_menu_item () {
    global $submenu;
    unset($submenu['upload.php'][17]);
}
add_action( 'admin_init', 'remove_media_categories_menu_item' );

If I’m correct, this is WP < 3.1 style. The WP > 3.1 remove_submenu_page( $menu_slug, $submenu_slug ) as follows didn’t work for me:

remove_submenu_page( 'uploads.php', 'edit-tags.php' );

and neither did

remove_submenu_page( 'uploads.php', 'edit-tags.php?taxonomy=category&post_type=attachment' );
