Application: kdeconnectd (21.12.2)

Qt Version: 5.15.2
Frameworks Version: 5.91.0
Operating System: Linux 5.17.0-rc5-1.ga9b2c1d-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 do not know who makes almost all X11 programs stop when there are two sessions on the same display, something that didn't happen before systemd times. (I've had to come back to X11 as Wayland likes to change to a display frequency out of range and I do not know how to recover from there).
It crashed after coming back to one X11 (Ctrl+Alt+F7) plasma session from another X11 plasma session (Ctrl+Alt+F8) after one night in the other X11 session (Ctrl+Alt+F8).

The reporter is unsure if this crash is reproducible.

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