Description Patrick Silva 2020-06-09 13:59:01 UTC

SUMMARY
crash reproducible on both Arch Linux (Plasma 5.19) and neon unstable.
The backtrace below was generated on neon unstable.

STEPS TO REPRODUCE
1. add a System Monitor widget to your desktop (I added the Disk Usage one)
2. right-click on the just added widget and open its settings window
3. select another "Display style" (I selected pie chart) and click on "Ok" button
(notice that the Disk Usage widget on desktop is empty)
4. right-click on the same widget and try to open its settings window (plasma crashes)

EXPECTED RESULT
no crash
