lxqt-config-monitor crashes on every login, every wake from sleep, and every
user launch of the settings module. It segfaults and coredumps, with kscreen.

Steps to Reproduce
    Log in to an LXQt session, or wake from sleep within one (not just from
screen lock)
    OR open l-c-monitor
    Check journalctl and look in /var/lib/systemd/coredump/ folder
    See the coredump and sefault reports from those times

Expected Behavior
l-c-monitor doesn't crash and coredump in any standard usage. If kscreen
crashes, l-c-monitor errors rather than crashing and coredumping.

Current Behavior
I don't have any particular need for l-c-monitor, since I use only one monitor,
my laptop display. But opening it shows a window that's blank as if there's no
detected display, and when I close it, it and kscreen segfault and coredump. If
I check journalctl, it shows similar segfaults and coredumps for l-c-monitor on
my user session login or wake from sleep, and the coredumps pile up in
/var/lib/systemd/coredump/

Since there's no user-facing option to disable l-c-monitor, the coredumps just
keep piling up.
