Same problem here with Fn-F10 (eject) and Fn-F3 (battery).
It also happens on my multimedia keyboard. Many of the multimedia keys work, but these do not:
sleep, stop, reload, Tools, Explorer
Pressing any of these keys results in the same "QT not supported" message.
I'm running ubuntu 9.04 with kde 4.3beta and qt 4.5.1
