-- Information about the crash:
- What I was doing when the application crashed:
I opened System Settings in icon view mode, I switched to sidebar view by clicking on the button on top,
closed System Settings with middle click on the task manager and Plasma shown a crash notification.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
