    Description

      The following logs are generated whenever an application attempts to recreate a QApplication/QWebView:

      QObject::connect: Cannot connect (null)::configurationAdded(QNetworkConfiguration) to QNetworkConfigurationManager::configurationAdded(QNetworkConfiguration)
      QObject::connect: Cannot connect (null)::configurationRemoved(QNetworkConfiguration) to QNetworkConfigurationManager::configurationRemoved(QNetworkConfiguration)
      QObject::connect: Cannot connect (null)::configurationChanged(QNetworkConfiguration) to QNetworkConfigurationManager::configurationChanged(QNetworkConfiguration)
      QObject::connect: Cannot connect (null)::onlineStateChanged(bool) to QNetworkConfigurationManager::onlineStateChanged(bool)
      QObject::connect: Cannot connect (null)::configurationUpdateComplete() to QNetworkConfigurationManager::updateCompleted()

      Note that this issue has been solved for QT 5.3.x in the following ticket:
      https://bugreports.qt-project.org/browse/QTBUG-36897

      However the issue remains within the 4.8.x branch. Many of us are still stuck on the 4.8.x branch and this is a pretty significant constraint.
