QBluetoothServer::hasPendingConnections() hangs on Windows

When connecting an Android client to a Bluetooth Windows server, inside the "clientConnected" slot, QBluetoothServer::hasPendingConnections() hangs (app not responsive).

To reproduce just add the following lines in the btChat exemple, at the beginning of ChatServer::clientConnected():

    qWarning()<<"checking pending connections ?";
    bool has = rfcommServer->hasPendingConnections();
    qWarning()<<"has pending connections ?"<<has;

Thanks,
Philippe
