Application: plasmashell (5.22.5)

Qt Version: 5.15.3
Frameworks Version: 5.86.0
Operating System: Linux 5.11.0-37-generic x86_64
Windowing System: X11
Drkonqi Version: 5.22.5
Distribution: Windowsfx 11

-- Information about the crash:
- What I was doing when the application crashed: Trying to add additional images to the desktop wallpaper gallery.

- Unusual behavior I noticed: I had already done this and was having to re-do it because my custom wallpaper had reverted to default. After opening the wallpaper settings, the custom wallpapers I had already added were no longer available. It crashed while the file browser was open to add them back.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
