Summary: Plasma crash when switching user from locked screen ->
freez of system

Reported In:

OS: Linux
Status: REPORTED

When trying to switch from one user to another when the screen is locked, then
system freezes and nothing else is possible, other than hard reboot of the
system.
STEPS TO REPRODUCE
1. Lock Screen
2. Click on switch user
OBSERVED RESULT
Everything freezes, nothing is possible anymore - no moving of mouse, no switch
to another tty-session. Hard reboot (via power-button) is required.
EXPECTED RESULT
I expect to be able to switch to my other user and login.

I thought to wait for the latest KDE Update, but since this issue is still
here, I need to post this issue here.
If anyone is able to help how I can share plasma logs from my system to see
what happens, I could share them here. There's also this bug which might, but
might not be related to that issue: https://bugs.kde.org/show_bug.cgi?id=511297
