[Qt-interest] sockets and threads on linux

[pmqt71]

Hi all,
Hi Qt people, I hope the best for Qt and you!

I have a tcp client server program working well on WinXP, but not on linux.

MyTcpServer inherits from QTcpServer. the incomingConnection method creates
a new socket and moves it to a new thread. The socket is handled by
MyTcpSocket that inherits from QTcpSocket and implements the slots to manage
client's incoming data:

void MyTcpServer::incomingConnection(int socketDescriptor)
{
   MyTcpSocket *pSocket = new MyTcpSocket();

   if (!pSocket->setSocketDescriptor(socketDescriptor)) {
       qDebug() << "MyTcpServer::incomingConnection:" << pSocket->error();
       return;
   }

   connect(pSocket, SIGNAL(readyRead()), pSocket, SLOT(onReadyRead()));
   connect(pSocket, SIGNAL(disconnected()), pSocket,
SLOT(onSocketDisconnect()));

   QThread *th = new QThread(this);
   pSocket->moveToThread(th);

   th->start();
}

On WinXP all is working fine, and I get the readyRead signal as a client
writes.
On linux (Ubuntu 9.04 64bit) the readyRead signal is not fired. The
incomingConnection is completed with no error, the pSocket objects gets the
event ThreadChange related to the moveToThread operation. Nothing else.
How can I debug?
Qt 4.6.2

thanks
