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

Application was not connecting to phone despite firewall disabled (ping also were passing). I renamed ~/.config/kdeconnectd and tried with fresh config- resulting in this crash. It persist after reboots.

The crash can be reproduced every time.
