Ok, now at least all widgets with a desktop widget as parent are created on the correct screen. But as soon as I open a child window (e.g. the file open dialog on my example) this is created on the applications primary screen.
Should I fill a bug report for this?

btw: Is it correct that QScreen::geometry() returns 0/0 every time (openSUSE 13.2/Qt 5.3.2 rpm)
