Hi all, KDE Frameworks 5 applications will install their translations into /usr/share/locale/$LANG the same way KDE 4 applications do. Then they will conflict. See also FS#41684 for more info. To fix this, we moved KDE 4 translations into /usr/share/locale/kde4/$LANG. This has been simple as rebuilding kdelibs and ALL applications using it. We rebuilt every package[1] which depend on kdelibs (directly or not), but someone could be missing. Please report any official package with a broken locale. You will need to rebuild your AUR packages that use kdelibs. Packages are in [testing] right now. Cheers [1] https://www.archlinux.org/todo/moving-kde4-translations/ -- Andrea Arch Linux Developer
