Interesting issue with KAboutData and icons

[Michael Pyne]

Hi all,

I received a bug (https://bugs.kde.org/show_bug.cgi?id=337938) reported 
against KAboutData in KCoreAddons, that setting the window icon doesn't 
actually set the window icon.

In fact, KAboutData doesn't even try to, except for setting a property to the 
string name of the icon in question.

However looking at it a bit more, that makes sense: KCoreAddons can't depend 
on QtGui or QtWidgets. So how is KAboutData supposed to set the application 
window icon now? Did this get shifted to a different Framework, or is Qt5 
supposed to handle it based on the property that was set?

Regards,
