Bug 447060

Application: kdeconnectd (22.03.70)
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.15.6-200.fc35.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 35 (KDE Plasma)
DrKonqi: 5.23.80 [KCrashBackend]

-- Information about the crash:
Built-from-source KDE Connect Daemon randomly crashes not clearly in response to anything I or the connected device was doing.

The top item in the clipboard at the time was:

kstart5 -- /home/nate/kde/usr/lib64/libexec/kdeconnectd --replace

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDE Connect Daemon (kdeconnectd), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
