The QApplication object is destroyed when the main function exists.
Your static MainWindow afterwards (by the c runtime exit).
The ScopedPointer crashing as a result of this is some instance used
by Qt internally (note the template arguments, it's for QObjectData).

As long as you have QWidgets you must have a QApplication object.
