KDE + LOCALE

I have been struggling trying to further understand why I can't get Chinese setup properly on my system (7.3) and during this process I noticed that my locale was set to 'C' (default). Trying to change this through the KDE Control Centre doesn't work. I change the settings. The settings take effect in that one window in the Control Center and I am prompted to log out and in of KDE. On logging back into KDE I find that the settings have been changed back to Default C. Anyone have any clue why this might be? Jethro
