Comment 2 for bug 1074371

There are same kind of bug reports:

https://bugs.launchpad.net/ubuntu/+source/language-selector/+bug/1066771
https://bugs.launchpad.net/ubuntu/+source/language-selector/+bug/1013626

bu not marking this as duplicate as the Kubuntu 12.10 language selector is broken in some cases. At here, the language selector is working as expected. The installation media was the mini.iso / MinimalCD: https://wiki.ubuntu.com/QuantalQuetzal/ReleaseNotes/Kubuntu

By the http://www.kubuntuforums.net/showthread.php?60590-Can-t-install-other-system-languages a workaround is to install the "kde-l10n-<language_code>" from the package manager.
