 (Compiled from sources)
Qt Version: 5.14.2
Frameworks Version: 5.70.0

Windowing system: X11
Distribution: Fedora 32 (KDE Plasma)

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

I am using plasma 5.18.90 on F32 built in copr: https://copr.fedorainfracloud.org/coprs/mkyral/plasma-unstable/

Though not official build, the contents is identical with what is being imported in Fedora Rawhide

Behaviour:

 * plasmashell crashes right after session start
 * plasmashell crashes when started from kicker
 * plasmashell crashes often (but not always) when started from konsole

Noteworthy detail:

 * when plasmashell starts, it runs fine
 * when plasmashell starts, it does not respect my locale settings (notable: language and time format)

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
