Bug#534166: Problem is way to KDE4
> 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.
Since you are using testing, you should not have packages from both
kde3 and kde4. Testing only has kde4 now. The missing kcmkttsd module
is not really missing, but you should use kde4's systemsettings to run
it. kcontrol only shows kcm modules from kde3. You can run it
separately if you want using the command "kcmshell4 kcmkttsd". If it
is still not opening, try running "kbuildsycoca4" as a user.
