For testing purpose I disabled it (remove the whole script from
startup). Currently it is enabled - I live with the 15 seconds delay at
startup. Until now no one could tell me why this module causes such a
delay and I was to lazy to check it out myself.

Aha -- this looks like the symptoms I've been seeing (https://bugzilla.redhat.com/show_bug.cgi?id=882506). But the problem persists after the startup sound too: all other KDE system sounds are delayed by about 1 second after the corresponding notification dialogue box, and running software such as gcompris (http://gcompris.net/) also shows a significant lag in all sounds.

I'll try getting rid of that module this evening (it's my home laptop) and see if that solves the problem ... Note that this issue doesn't appear on an identical computer with F17 + kde-unstable updates.
