I just tried with a freshly created user, and it worked the same. (with notification-daemon installed, not notify-osd; it even worked with none of both installed as I mentioned earlier)

But it is of course possible that a default fresh KDE installation is missing a required package (that I happen to have installed, I do have GNOME installed as well f.e.).
That would be a packaging bug then I'd say (missing dependency for some package, libnotify-tools or libnotify4 maybe?)

I don't want to do a fresh install right now, but I may try that at the weekend maybe.
