Bug 495967

Application: kdeconnectd (24.08.0)

Qt Version: 6.7.2
Frameworks Version: 6.6.0
Operating System: Linux 6.10.11-200.fc40.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 40 (KDE Plasma)"
DrKonqi: 6.1.5 [CoredumpBackend]

-- Information about the crash:
I was working on laptop with bluetooth connected to headphones and Android phone. Actually, I didn't interact with KDE Connect, but at the same moment of crash all connected bluetooth devices have disconnected.

The crash can be reproduced sometimes.
