Timing Issue: QSslCertificate can NULL when receiving SSL errors from QNetworkReply

Any CA certificates are removed:

QList<QSslCertificate> certificates;

QSslConfiguration config = QSslConfiguration::defaultConfiguration();

config.setProtocol(QSsl::TlsV1);
config.setCaCertificates(certificates);

QSslConfiguration::setDefaultConfiguration(config);

A QWebView is instantiated:

QWebView *browserWebView = new QWebView(this);
browserWebView->show();

QNetworkAccessManager *network = new QNetworkAccessManager();
browserWebView->page()->setNetworkAccessManager(network);

connect(network, SIGNAL(sslErrors(QNetworkReply*,QList<QSslError>)),
SLOT(sslErrorsMethod(QNetworkReply*,QList<QSslError>)));

browserWebView->load(QUrl("https://.....")); #a page wich contains multiple images from different https site's

void MainWindow::sslErrorsMethod(QNetworkReply *reply,QList<QSslError> list)
{
for(int i=0;i<list.size();i++)

{ qDebug("%s",list.at(i).errorString().toAscii().data()); }

if (config.peerCertificate().isNull())
qDebug("--------------sslErrorsMethod: peer certificate is null!!!");

sleep(2);
}

This is the output:

SSL Errors
The issuer certificate of a locally looked up certificate could not be found
The root CA certificate is not trusted for this purpose
--------------sslErrorsMethod: peer certificate is null!!!

SSL Errors
The issuer certificate of a locally looked up certificate could not be found
The root CA certificate is not trusted for this purpose

SSL Errors
The issuer certificate of a locally looked up certificate could not be found
The root CA certificate is not trusted for this purpose
--------------sslErrorsMethod: peer certificate is null!!!

It is pretty random, sometimes is ok sometimes is not.
NOT OK means to have a NULL certificate in replay when sslError slot is called

Thank you
