Bug 413226

Application: plasmashell (5.17.0)

Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 5.3.5-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Wallpaper settings were changed for the first time in a new activity. A folder containing the images for the slideshow was added. Plasma crashed as soon as the settings were applied, however the settings appear to have been applied.

- Custom settings of the application:
New activity with Folder View and Notes widgets.

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