still crasing in plasma 5.12.2
I'm switching to Manjaro KDE 18.0.3 and still encounter this issue. But I found out what happened, it doesn't apply to any specific languages, it just that it automatically crashes when you add the third language, no matter what is that. I tried multiple language and got the same problem when adding the third one. You can only add 2 languages there.
Regional Settings cause systemsettings to freeze do to a bad kcm_translations.so in /usr/lib64/qt5/plugins/kcms
This ticket is about a crash. For the freeze, please see bug 405001.

Let's assume it was a Qt bug; changing status. If you see this again, please add a comment or reopen this ticket.
weirdly the crash is happening again when I add a CJK language at the bottom of the list. :( Operating System: Arch Linux KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.65.0 Qt Version: 5.14.0

> Can someone write here URL of upstream Qt bug? My conclusion came from the statement in comment 20. I don't know if there is an upstream ticket.
