MonoTorrent mode and metadata

The MonoTorrent client does not download a file from another partner using the matadata mode:

var torrentDefaults = new TorrentSettings {
   UseDht = true, 
   EnablePeerExchange = true
};
var engine = new ClientEngine();

engine.ChangeListenEndpoint(new IPEndPoint(IPAddress.Any, port));

var dhtListner = new DhtListener(new IPEndPoint(IPAddress.Any, port + 1));
var dht = new DhtEngine(dhtListner);


var infoHash = InfoHash.FromHex("07E45F689860166CC41E44C8F07901E3E8D27D42");
var announces = new[] {
   new RawTrackerTier(new[] {"http://somehostname:8080/announce"})
};

var torrentManager = new TorrentManager(
   infoHash, downloadsPath, torrentDefaults, torrentsPath, announces);

engine.Register(torrentManager);

engine.RegisterDht(dht);
dhtListner.Start();
engine.DhtEngine.Start();
engine.StartAll();

If I use a torrent file with metadata, everything works fine.
