 should be:


 {{{
         foreach ( $wp_filter[$tag] as $filter ) {
                 foreach( (array) $filter as $the_ )
                         if ( !is_null($the_['function']) ){
                                 $args[1] = $string;
                                 $string =
 call_user_func_array($the_['function'], array_slice($args, 1, (int)
 $the_['accepted_args']));
                         }
         }

 }}}

 because if you use remove_filter() at some point, you can end up with an
 empty array on $wp_filters[$tag]. using while ( next($wp_filters[$tag]) )
 at that point ends up ignoring a whole batch of applicable filters.
