Sometimes Certain Feeds Aren't Updated

i suspect it's when the feeds are missing titles, and then the item gets assigned the value 'NULL_EMPTY'. i had to add "&& $item != 'NULL_EMPTY'" on the if-statement in this block of code in simpleblogroll.module:

function _simpleblogroll_modify_db($op, $feedurl = '') {
      ...
      case 'update':
        if ($item != '' && $item != 'NULL_EMPTY') {
          $query_check_for_item = db_query('SELECT feed_title, last_item '
              .'FROM {simpleblogroll} '
              ."WHERE last_item = '%s'",
              $item
              );
      }
      ...
}
