Bug 423252

Application: dolphin (20.07.70)

Qt Version: 5.15.0
Frameworks Version: 5.72.0
Operating System: Linux 5.7.2-zen1-1-default x86_64
Windowing system: Wayland
Distribution: "openSUSE Tumbleweed"

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

Created a folder named s in ~/Building.
Opened a compress file with ark, in my case the sources for zen kernel.
Drag the sources folder into s from ark's window.

- Unusual behavior I noticed:

Ark goes into a not responding state, around this point is when the dolphin crash happens, sometimes the sad face pops more than once. 
The decompressing task still going though and afer a while i get the notification status bar for the task which completes OK.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
