[Plugin: The Subtitle] Notice: Undefined index: the_sub_nonce

I was getting the following notice while using version 1.2 of The Subtitle plugin:
Notice: Undefined index: the_sub_nonce in /path/to/www/wp-content/plugins/the-subtitle/the-subtitle.php on line 112

I removed the notice by changing line 112 to:

if (!isset($_POST['the_sub_nonce']) || !wp_verify_nonce( $_POST['the_sub_nonce'], plugin_basename( __FILE__ ) ) )
 		return;

Seem right?
