      Steps to reproduce (qtbug36958.zip):

      • Launch app, press "Copy Custom Mime DAta"
      • Quit
        Note assert: 
        MyDialog::MyDialog
MyMimeData::MyMimeData
MyDialog::slotCopyCustomMimeData QMimeData(0x5c032f0590)
MyMimeData::formats ("application/x-qt-image")
MyMimeData::retrieveData "application/x-qt-image" QVariant::QImage
MyMimeData::retrieveData returns QVariant(QPixmap, QPixmap(QSize(32, 32) )  )
MyMimeData::formats ("application/x-qt-image")
MyDialog::~MyDialog
MyMimeData::formats ("application/x-qt-image")
MyMimeData::retrieveData "application/x-qt-image" QVariant::QImage
QCoreApplication::arguments: Please instantiate the QApplication object first
QPixmap: Must construct a QGuiApplication before a QPixmap

        Same problem exists in Qt 4, but it does not crash.
