-- Information about the crash:
A similar incident happened when setting up the WallpaperEngine plugin, it seems that there are certain wallpapers that contain elements that will cause a crash. I'm not sure what elements, but the solution that worked for me before was to edit `plasma-org.kde.plasma.desktop-appletsrc` and to change the selected wallpaper there to a different item. I had no further issues at the time, but this makes me think it is something more than just a selected wallpaper.

Regardless, this appears to be more of an issue with the WallpaperEngine plugin than with Plasmashell.

The crash can be reproduced every time.

-- Backtrace:
