Application: kdeconnectd (1.4.0)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-3-amd64 x86_64
Distribution: Debian GNU/Linux bullseye/sid

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

I opened WhatsApp to copy a link to the clipboard, but KDE connect crashed before I got that far.
I have tried to copy this link several times, but to no avail.
I did manage to start playing music in clementine on my desktop using the KDE connect app on my phone.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE-Connect-daemon (kdeconnectd), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
