QLocalServer incomingConnection method never calls, but newConnection signal sent

[ocgltd]

I am creating a simple QSocketServer in Qt. The socket starts to listen, but the incomingConnection method never seems to run. Can someone explain what is wrong here?

in main:

m_pipeserver = new PipeServer(this);  
if (m_pipeserver->listen("test.sock")) { 
    qDebug() << "STARTED";
}

m_pipeserver = new PipeServer(this);  
if (m_pipeserver->listen("test.sock")) { 
    qDebug() << "STARTED";
}

in pipeserver.h

class PipeServer : public QLocalServer
{
    Q_OBJECT
public:
    PipeServer(Controller *parent = 0);
protected:
    void incomingConnection(qintptr socketDescriptor);

class PipeServer : public QLocalServer
{
    Q_OBJECT
public:
    PipeServer(Controller *parent = 0);
protected:
    void incomingConnection(qintptr socketDescriptor);

pipeserver.cpp

PipeServer::PipeServer(Controller *parent) 
{
}
void PipeServer::incomingConnection(qintptr socketDescriptor)
{
    qDebug() << "NEW CONNECTION";
    // etc...

PipeServer::PipeServer(Controller *parent) 
{
}
void PipeServer::incomingConnection(qintptr socketDescriptor)
{
    qDebug() << "NEW CONNECTION";
    // etc...

I see the STARTED message, but never see the NEW CONNECTION when I run:

socat -v READLINE unix-connect:/tmp/test.sock

Just for fun I hooked a slot method onto the newConnection signal and that method DOES fire when I connect. So why isn't the incomingConnection method firing?
