That was a useful tip, thanks Lubomir. Not out of the woods yet but an 
interesting observation:

Kirigami.ApplicationWindow {
	id: rootItem
	title: "Subsurface-mobile"
}

gives same problem, but

ApplicationWindow {
	id: rootItem
	title: "Subsurface-mobile"
}

passes the hard exit. So, there is some relation to Kirigami.  However, 
all this just does not happen on Qt 5.9.1 but only on 5.9.2.
