STEPS TO REPRODUCE
1. start Wayland session
2. add weather report widget to your desktop
3. right click on wallpaper, select "Configure desktop..."
4. change plasma layout setting and click on "Ok" button
5. do not minimize/close "Configure desktop..." window, drag and drop the weather report widget on your desktop. If plasma does not crash, drag and drop the widget a few times again. At some point probably plasma will crash.

EXPECTED RESULT
no crash
