Hi there! Got a little problem with the localization, maybe you got some ideas

: I got a fresh installation of PCLOS 2013 with all updates and KDE 4.10.1, and after running addlocale, KDE refuses to use the new localization, it says in an information message "
You have the language with code 'de' in your list of languages to use for translation but the localization files for it could not be found. The language has been removed from your configuration. If you want to add it again please install the localization files for it and add the language again.".
Only KDE is affected, the rest (PCC, scripting, even the welcome message while booting when you turn off plymounth) is in local language [=German]. I also booted a live CD with KDE 4.9.5 and run the addlocale, but with the same result: the script is finished all right, but on log on there's the same message again.
I checked synaptic, locales and locales-de are both installed. What does KDE want me to do? Which files must be placed where?
So now I ended up with a mixture of German and English - most anoying, I would like to fix it asap! Any ideas anyone?
I('m open to suggestions...

Live Long and Prosper in the Spirit of Sheng Zhen - and Have a lot of fun!
