Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: tgeor....@gmail.com
Target Milestone: ---
Application: systemsettings5 (5.18.3)

Frameworks Version: 5.68.0
Operating System: Linux 5.3.0-40-generic x86_64

effects.
The crash can be reproduced sometimes.
