Description pub 2020-05-08 17:53:04 UTC

Application: plasmashell (5.18.3)

Qt Version: 5.13.2
Frameworks Version: 5.68.0
Operating System: Linux 5.6.8-300.fc32.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 32 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:

I was tring to configure locales by `localectl set-locale`. 'System settings' app doesn't provied enough localization settings and contain bugs. So I decided to use CLI and set every env variable manualy. I used `localectl set-locale` for LANG LANGUAGE and every LC_*. Plasma crashed just after I pushed logout button.

Such crash happend before. I'm not sure about the circumstances but I was using `localectl set-locale` in console just before that crash

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
