Application: kdeconnectd (22.12.2)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.10-273-tkg-pds x86_64
Windowing System: Wayland
Distribution: EndeavourOS
DrKonqi: 5.27.1 [KCrashBackend]

-- Information about the crash:
Sometimes when attempting to pair from my Fedora 36 laptop running GSConnect, the KDE Connect daemon on the host computer will crash. I noticed a mention of mpris in the crash log, and I was using an application that supports it on the host computer (specifically Cantata); however, I was playing back a radio stream without any album art.

The crash can be reproduced sometimes.

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