Code

  // If a node is being deleted, ensure it's also removed from any queues.
  $result = db_query("SELECT qid, sqid FROM {nodequeue_nodes} WHERE nid =:nid", array(

  ));
  foreach ($result as $obj) {

    // If the queue is being tracked by translation set and the node is part
    // of a translation set, don't delete the queue record.
    // Instead, data will be updated in the 'translation_change' op, below.

      // node in a queue twice, the 2nd position would be wrong.
