I would say that most users would start changing settings if they find
their settings are gone.

Also, other data files, such as the user's entire jigsaw puzzle collection in
Palapeli, the saved solution-state of each puzzle, the saved state of a cube
in Kubrick and any games or levels in KGoldrunner that are being composed
or edited by the user --- to name a few.

Yes, it is a really serious problem, IMHO.

Hope that works in all cases.  Well spotted, Mathias!
