#31983: Php warning

 The problem is on wp-includes/shortcodes.php line 280: it may sometimes
 generates warnings because $m[5] is set but $shortcode_tags[$tag] is not
 set.

 Just add those three lines after line 278:


 {{{
 279     if (!isset($shortcode_tags[$tag])) {
 280         return false;
 281     }

 }}}


 So no warning is raised. Here's a sample of the warning raised - just in
 case:
