Application crashes on waitForConnected when using a proxy

[elmi]

Hi All,

I created a small application to test a network connection. Everything worked fine if I don't use a proxy.
If I use a proxy and use wrong proxy settings i got a error message. If I use the correct proxy settings the application crashes.
Maybe someone can provide me help.

Here is my code:

The proxy settings:
@
proxyTCP = new QNetworkProxy();

    proxyTCP->setType(QNetworkProxy::HttpProxy);

    proxyTCP->setHostName(pdes);
    proxyTCP->setPort(port_int);

    if (user != NULL && !user.trimmed().isEmpty())
        proxyTCP->setUser(user);
    if (pw != NULL && !pw.trimmed().isEmpty())
        proxyTCP->setPassword(pw);

@

The connection:
@
socket = new QTcpSocket(this);

if (proxyTCP != NULL)
{
    socket->setProxy(*proxyTCP);
}

socket->connectToHost(des, port_int);


if (socket->waitForConnected(5000)) // The application chrashes here
{
    emit processEnded(1, type, "Success", true);
}
else
{
    emit processEnded(0, type, socket->errorString(), true);
}

@

Thanks
Elmi
