Notice: Undefined index: title in zentropy_links() (line 891 of /var/www/dev/cccj/sites/all/themes/zentropy/template.php).

Hi

Drupal started throwing up an error as in the title:

Notice: Undefined index: title in zentropy_links() (line 891 of /var/www/dev/cccj/sites/all/themes/zentropy/template.php).

I found the line in the template which is trying to find a title key whilst going over menu items, and looks like it can't find the key.
I just did something below, to check if the key exists and if not add nothing which made the error go away.
Perhaps you'll be able to put in something better written to accomodate this issue.

 $custom_class = "";
       if (isset($link['title'])) {
        $custom_class = drupal_html_class($link['title']);
       }
       // Add extra class to menu items.
      //$custom_class = drupal_html_class($link['title']);
      $class[] = $custom_class;
      $output .= '<li' . drupal_attributes(array('class' => $class)) . '>';
