Well, that dynamic property call is supposed to catch this static property 
from QGuiApplication, provided that qApp is not just a QCoreApplication:

  Q_PROPERTY(QIcon windowIcon READ windowIcon WRITE setWindowIcon)

I made this stuff work in qtbase f42bd772f8110dba13d209d81d8eed0077772185,
which is in Qt 5.3.0.

So it's known that it won't work with older versions of Qt.

I didn't test it via KAboutData though.
