Kubuntu 11.10 beta: systemsettings crashes when changing kde system language

I have Kubuntu 11.10 beta installed on my laptop.

If I try to change the system language the systemsetting application crashes every time.

me@zwerg:/dev$ systemsettings(6653): No language dictionaries for the language : "de"

systemsettings(6653)/python (plugin): Error while running factory function for Python plugin: "language-selector/language-selector.py"

systemsettings(6653)/kcontrol KCModuleLoader::loadModule: This module has no valid entry symbol at all. The reason could be that it's still using K_EXPORT_COMPONENT_FACTORY with a custom X-KDE-FactoryName which is not supported anymore
X Error: BadWindow (invalid Window parameter) 3
  Major opcode: 20 (X_GetProperty)

How can I fix this? Is this a Bug?

Thanks!
