--- Comment #1 from Axel Braun <axel.br...@gmx.de> --- I did some more investigations on this. Even if you set British English as second language, some programs (VLC for example) come up in German The issue is that ~/.config/plasma-localerc the entry in [Formats] still has the system-wide setting (de_DE.UTF-8 in my case) Switching this MANUALLY to LANG=en_US.UTF-8 gives finally the desired result. EXPECTED BEHAVIOUR When selecting a language in KDE regional settings as primary language, all required settings are properly set by KDE -- You are receiving this mail because: You are watching all bug changes.
