My Problem
I compiled OpenSSL into QT to enable OpenSSL support. Everything appeared to go correctly in the compile.

However, when I try to use the official HTTP example application that can be found here, everytime I try to download an https page, it will signal two QSslError, each with contents NoError.

The types of QSslErrors, including NoError, are documented here, poorly. There is no explanation on why they even included an error type called NoError, or what it means.

Bizarrely, the NoError error code seems to be true, as it downloads the remote https document perfectly even while signaling the error.

Does anyone have any idea what this means and what could possibly be causing it?

Optional Background Reading
Here is the relevant part of the code from the example app (this is connected to the network connection's sslErrors signal by the constructor):

void HttpWindow::sslErrors(QNetworkReply*,const QList<QSslError> &errors)
{
 QString errorString;
 foreach (const QSslError &error, errors) {
     if (!errorString.isEmpty())
         errorString += ", ";
     errorString += error.errorString();
 }

 if (QMessageBox::warning(this, tr("HTTP"),
                          tr("One or more SSL errors has occurred: %1").arg(errorString),
                          QMessageBox::Ignore | QMessageBox::Abort) == QMessageBox::Ignore) {
     reply->ignoreSslErrors();
 }
}

I have tried the old version of this example, and it produced the same result.

I have tried OpenSSL 1.0.0a and 0.9.8o. I have tried tried compiling OpenSSL myself, I have tried using pre-compiled versions of OpenSSL from the net. All produce the same result.

If this were my first time using QT with SSL, I would almost think this is the intended result (even though their example application is popping up error warning message windows), if not for the fact that last time I played with QT, using what would now be an old version of QT with an old version of SSL, I distinctly remember everything working fine with no error windows.

My system is running Windows 7 x64.
