The problem is that the packages are now screwed to KDE 4.2.2. So there is a Mixup from KDE 3 and KDE 4! It is not surprising that this is not working. As solution i downloaded manually the correct packages from stable and installed them manually: dpkg -i kttsd dpkg -i kttsd-contrib-plugins_3.5.9-2_amd64.deb dpkg -i ksayit_3.5.9-2_amd64.deb Now it is working a little bit again, but not complete.
