Regression: Qt Applications crash on exit when destructor of global QPixmap container is called

 
#include <QtGui>

QHash<QString, QPixmap> pixmapCache;

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    pixmapCache.insert("bla", QPixmap());

    QWidget w;
    w.show();
    return a.exec();
}
