Application: dolphin (19.12.3)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.8.0-50-lowlatency x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was on the desktop (the one with the wallpaper, not inside Dolphin itself) and had selected a file with the mouse, then used "Del" key to delete it. it showed the "Deleting file" notification, and then when it showed the "File deleted" notification there appeared immediately also a notification that "Dolphin has crashed". I think this problem has also appeared more than once, but i don't know when it happens. It is not like each time i delete a file this happens and i don't know if i can ever reproduce this intentionally. Just happens sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
