Description Jacky Cheong 2022-05-19 18:26:31 UTC 
Application: kdeconnectd (21.12.2)

Qt Version: 5.15.3
Frameworks Version: 5.93.0
Operating System: Linux 5.17.7-1.surface.fc36.x86_64 x86_64
Windowing System: X11
Distribution: "Fedora release 36 (Thirty Six)"
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- Unusual behavior I noticed:

I use kde-connect on plasma and gnome, I auto start it it by gnome settings and systemctl service.

I also auto start by KDE-plasma (/etc/xdg/autostart/org.kde.kdeconnect.daemon.desktop)

Before I update to Fedora 35, I set my PC name as F35, also set kde-connect name as F35. After I updated to Fedora 36, I change both to 36.

However, when I opened "KDE-Connect Settings" on PC, the old one "F35" appears on the list. Which is very weird, I shouldn't be able to connect to my PC from my PC. So when I click pair with "F35"

The kde daemon crashed. (/usr/libexec/kdeconnectd)

The crash can be reproduced every time.

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