Notice error in runqueue.sh - queue_defaults

I sometimes get this error:

Notice: Undefined variable: queue_defaults in <em class="placeholder">beanstalkd_process_item()</em> (line <em class="placeholder">122</em> of <em class="placeholder">/var/www/html/SITE/webroot/sites/all/modules/contrib/beanstalkd/runqueue.sh</em>).

Code in question:

function beanstalkd_process_item($item) {
  global $queue;

  $info = beanstalkd_get_host_queues(NULL, $item->name);

  if (!empty($info)) {
    $function = $info['worker callback'];

    try {
      beanstalkd_log(t("Processing job @id for queue @name", array('@id' => $item->id, '@name' => $item->name)));
      if (isset($info['description callback']) && function_exists($info['description callback'])) {
        beanstalkd_log($info['description callback']($item->data));
      }

      ini_set('display_errors', 0);
      $function($item->data);
      ini_set('display_errors', 1);

      return TRUE;
    }
    catch (Exception $e) {
      beanstalkd_log(t('Exception caught: @message', array('@message' => $e->getMessage())));
      $stats = $queue->statsJob($item);
      if ($stats['releases'] < $queue_defaults['retries']) {
        $queue->release($item, $queue_defaults['priority'], $queue_defaults['release_delay']);
      }
      else {
        $queue->bury($item);
      }
      return FALSE;
    }
  }
}

Looks like, at first glance, the defaults are not being pulled in.

Maybe we need to add this in somewhere?

$queue_defaults = beanstalkd_get_queue_options($item->name);
