Bug 496753

Application: kdeconnectd (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-27-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
After the downgrade from KDE Connect 20.12.3-2 to 22.12.3-1, it segfaults every time after (semi- successfully, presumably) pairing with a phone using Valent. After it is restarted, both the phone and KDE show the other peer as disconnected.

The crash can be reproduced every time.

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