Description Tony 2020-11-01 09:36:39 UTC 
Application: dolphin (20.11.70)

Qt Version: 5.15.1
Frameworks Version: 5.76.0
Operating System: Linux 5.9.1-1-default x86_64
Windowing system: Wayland
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:

Opened dolphin, hit crtl+I and type "z".

The frequency of the crash varies depending on how dolphin is launched. 
Using Meta+E it will crash everytime.
Using the taskbar/desktop shorcut, from the application launcher or from a terminal it needs 2 or 3 tries of launching it and closing it until the crash accurs.

Oddly enough it does not happen if launched from krunner.

The crash can be reproduced every time.

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