Bug 453580

Application: kdeconnectd (22.07.70)

Qt Version: 5.15.3
Frameworks Version: 5.94.0
Operating System: Linux 5.15.0-27-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04 LTS
DrKonqi: 5.24.80 [KCrashBackend]

-- Information about the crash:
the kdeconnect service crashes after a short while regardless of what is going on. Whenerver I start a kdeconnect operation, such as through the CLI or the plasma icon, after a few seconds kdeconnectd crashes and I get a crash report dialog.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Connect Daemon (kdeconnectd), signal: Segmentation fault
