Jaunty kde3 remix - no application icons in kicker

Hi, I recently made an upgrade from Hardy to Jaunty on my laptop (Intel-X86 packages). Since KDE4 doesn't provide the full functionality of KDE3 I installed kubuntu-desktop-kde3 following the instructions given on https://wiki.kubuntu.org/Kubuntu/Kde3/Jaunty to get a system with two parallel desktops. After kicking out some leftover Hardy-packages I eventually managed to get a working KDE-3.5.10. But KDE3 started with an empty KDE panel. I first had to add applets like "Clock", "K Menu", "Show Desktop", "Taskbar", "Trash" etc. again to get what I used to have before the upgrade. The only thing still missing are the icons of programs like "kalarm", "kpowersave", "kmix", "kgpg" etc. All of these programs are running on my system either in the KDE3 or KDE4 version. But none of them seem to register with kicker under KDE3 whereas the icons appear in the panel of KDE4. How can I fix this problem? Thanks Knut
