iTunes item description bug

An important element for the item's description is having properly setup tags especially the itunes:summary. Although I setup a field for my description, it was only pulling in the description tag and not the itunes:summary tag. I made the folllowing adjustment to views_podcast_views_type.inc:

// Prepare the item description -- moved down below the itunes duration code block so that $privateExtra would be defined
    if (isset($view_podcast->item_itunes_summary_override) && 
        $view_podcast->item_itunes_summary_override != "") {
      $description = $view_podcast->item_itunes_summary_override;
    }
    else if (isset($view_podcast->item_itunes_summary) && 
            $view_podcast->item_itunes_summary != "") {
      $tempa = str_replace(".", "_", $view_podcast->item_itunes_summary);
      $tempb = eregi_replace(".*\.", "", $view_podcast->item_itunes_summary);
      if (isset($node->$tempa)) {
          $description = $node->$tempa;  //Field exists in View data
					$privateExtra[] = array(
          	'key' => 'itunes:summary', 
          	'value' =>  $node->$tempa);  //Field exists in View data
      } 
      else if (isset($item->$tempb)) {
          $description = $item->$tempb;  //Field exists in Node data
					$privateExtra[] = array(
          	'key' => 'itunes:summary', 
          	'value' =>  $item->$tempb);  //Field exists in Node data
      } 
      else {
        $description = '';
      }
    }
    else {
      $description = '';
    }
