https://bugreports.qt-project.org/browse/QTBUG-32168
because of this bug I don't recommend to use MinGW

[Pavel_Osipyants]

@QString directory = QStandardPaths::writableLocation(QStandardPaths::DataLocation);
if (directory.isEmpty())
directory = QDir::homePath() + QLatin1String("/.") + QCoreApplication::applicationName();
QWebSettings::setIconDatabasePath(directory);
QWebSettings::setOfflineStoragePath(directory);
QWebSettings::globalSettings()->setAttribute(QWebSettings::PluginsEnabled, true);@

I also recommend to use this snippet to avoid problems with webkit
