    Description

      Qt plugin instances are never deleted. For example when loading a SVG document, the svg plugin is loaded and the QSvgPlugin object is constructed, however it is never deleted.

      int main(int argc, char *argv[])
{
    _CrtSetDbgFlag( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );

    QApplication a(argc, argv);
    QIcon icon = QIcon("C:/qt/4.5.1/demos/browser/data/browser.svg");

    return 0; //a.exec();
}
