No.

The platform plugin will load KDE libraries and those will do whatever they 
want. In other environments (Maemo, MeeGo, Symbian), the libraries from those 
systems will do what they want too.

The problem is not in Qt nor in your application.

The problem is in KDE Libraries. It must be solved there. Those messages 
should not be printed, so they are either KDE bugs or bugs in your 
distribution for enabling them by default.

If you build Qt without D-Bus, instead of getting annoying stderr messages on 
startup, you'll get crashes.
