Do you know why this would cause https://bugs.kde.org/show_bug.cgi?id=437791 ? 1 line window if there's no konsolerc

@hindenburg I believe the actual culprit was identified as frameworks/kxmlgui!53 (merged), which this change just exposed.

Well, sort of. That change didn't break other apps, just Konsole. So it seems like Konsole is doing something odd with its window sizes to trigger the issue with the new code there.

This is how setupGUI() works and was reverted meanwhile.
Exact reason is still yet to be known.
