menu lettering partly in Russian

On my Ubuntu 9.10 with KDE 4.3.2 I have installed additional languages (US English, Russian, Turkish, Czech and Hungarian). I use normally German language.
In the moment I get KDE menus in German and Russian language (mixed)!
E.g. in the menu "KPackageKit" and in the menu "Land/Region & Sprache - Systemeinstellungen".

Kind regards
Helmut

Appendix:
The problem still exist.
The behavior still is more inprobable.
I get menus not only in German and Russian but also popups in Czech!
In addition I get menus in Hungarian (Verbindungen verwalten – DSL bearbeiten).
The languages are mixed completely.
I will try to reinstall all languages.
