• OpenSim/Region/ClientStack/LindenUDP/LLPacketHandler.cs
• QueuePacket() の item.Length = packet.Length; で例外発生
• ParcelObjectOwnersReplyPacket には get_Length() が実装されていないと言うこと？
• 原因不明だが，とりあえず，例外を catch して回避

  private void QueuePacket(
          Packet packet, ThrottleOutPacketType throttlePacketType,
          Object id)
  {   
      LLQueItem item = new LLQueItem();
      item.Packet = packet;
      item.Incoming = false;
      item.throttleType = throttlePacketType;
      item.TickCount = Environment.TickCount;
      item.Identifier = id;
      item.Resends = 0;
      try {
          item.Length = packet.Length;
      }
      catch (Exception e) {
          item.Length = 0;
      }
      item.Sequence = packet.Header.Sequence;
  
      m_PacketQueue.Enqueue(item);
      m_PacketsSent++;
  }
