-- Information about the crash:
- What I was doing when the application crashed:
Started plasma (X11). Phone is on same WiFi network and running app.
App on phone does not connect.
KDE connect hits a segfault sometimes (rarely though)

Restarting KDE connect seems to fix it.

kdeconnect-settings, kdeconnect-sms, kdeconnect-cli, and kdeconnect-handler version is 21.12.1
(kdeconnect-app version is 1.0 but from same RPM)

RPMs - OpenSUSE:
kdeconnect-kde-zsh-completion-21.12.1-1.1.noarch
kdeconnect-kde-lang-21.12.1-1.1.noarch
kdeconnect-kde-21.12.1-1.1.x86_64

KDE (plasmashell) version 5.23.5 running on X11 with dual monitors.
Breeze icon theme.
