Sentry Crash Report:

Description sstsoft 2019-02-06 07:32:12 UTC 
Application: plasmashell (5.12.6)

Qt Version: 5.9.4
Frameworks Version: 5.45.0
Operating System: Linux 4.12.14-lp150.12.45-default x86_64
Distribution: "openSUSE Leap 15.0"

-- Information about the crash:
- Custom settings of the application:
KWin5 got OpenSTEP custom theme, but regardless of using Breeze right now, KDE apps suych as Main Menu customizer, Plasma applet customize, Window border customizer crashed each time. Although it happened after /home/user dir reused after clean SUSE install. This shouldn't happen. Changed user rights, removed .config dir, but regardless this crap still crashes, at the beginning startup screen refused to show, startup scripts were probably invalid or KWin refused to lunch. 
LXQT worked, XFCE worked (reused settings) but not KDE

The crash can be reproduced every time.

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

Comment 1 Christoph Feck 2019-02-22 18:47:11 UTC 
Try: rm -r ~/.cache/*/qmlcache

Removing the .config will not clean the QML caches. I think newer versions of distributions know this issue, and detect caches from mixed Qt versions.
Comment 2 David Edmundson 2021-03-01 23:09:28 UTC 
Crash is in Qt and this is against a really old version
