Bug 450907

Application: kdeconnectd (21.12.2)

Qt Version: 5.15.2
Frameworks Version: 5.91.0
Operating System: Linux 5.16.4-1-default x86_64
Windowing System: X11
Distribution: openSUSE Tumbleweed
DrKonqi: 5.24.2 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

I think I disabled wifi when the crash happened. One thing to note is, that I was trying out the iwd backend (which btw does absolutely not work)

The reporter is unsure if this crash is reproducible.

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