Application: dolphin (19.12.3)

Qt Version: 5.14.1
Frameworks Version: 5.69.0
Operating System: Linux 4.15.0-96-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
- What I was doing when the application crashed:
I tried to resend a file via Bluetooth to a Win10 maschine, but file acceptance was denied by Win10.
The behavior is reproduceable on my KDE NEon maschine (latest updates installed)

The crash can be reproduced every time.

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