[Interest] QSopedPointer crashes application at exit

[Nils Jeisecke]

Hi,

> The problem is in QScopedPointer at exit point
I don't think this has something to do with the QScopedPointer.

The QApplication is object is destroyed before the static instance of
your MainWindow is.
The QWidget destructor however needs a QApplication instance (see
stack frame #3).
