Bug 442154

Application: plasmashell (5.18.6)

Qt Version: 5.12.7
Frameworks Version: 5.76.0
Operating System: Linux 5.3.18-59.19-default x86_64
Windowing system: X11
Distribution: openSUSE Leap 15.3

-- Information about the crash:
- What I was doing when the application crashed: I was attempting to download some new wallpapers to install on a new user's desktop. I opened the Configure Desktop app and clicked on the Get New Wallpapers button. I then typed "moon craters" into the search box and a wallpaper appeared, although I only saw the text with the name and description of the wallpaper, there was no image of the wallpaper. I clicked on the install button for the moon craters wallpaper and the Configure Desktop crashed and closed and there was only the desktop again with no error message until I received the message asking if I would report this with the KDE Crash Handler.

- Unusual behavior I noticed:  Nothing out of the ordinary until the crash. I tried downloading wallpapers again and was successful, although I did encounter several error messages, but the Configure Desktop app did not crash again. I used Spectacle to make screenshots of the error messages I received during my second, successfull attempt to download wallpapers and I will try to upload the screenshots if there is a way to do that during this crash report.
