Comment # 1 on bug 1000652 from Wolfgang Bauer

The translations for bundle-lang-kde-xx are just taken from the "normal"
translation packages.

In this case the translations are part of the package plasma5-pk-updates
itself, in the package plasma5-pk-updates-lang.

You already filed a bug report about them being outdated, marking as duplicate.

But it would be nice if you could tell where/how to best get the latest
translations.
I don't really want to download them manually from SVN for every single
language if it would be avoidable. (I actually only found them in SVN a few
days ago anyway... otherwise I may have updated them already)
