Bug#970515: kde-plasma-desktop: Can't switch user in current session

[Max Hofer <max-hofer@gmx.net>]

Package: kde-plasma-desktop
Version: 5:106
Severity: normal

Dear Maintainer,

until a couple weeks ago I could switch from the current KDE session to another
user by using a button 'Switch user', which would open a new X session, without
destroying my original KDE session I was on.

I belive (not sure) since the upgrade from 5:105 -> 5:106 this button disapeared.

To switch the user I have to leave the current session (logout).

Searching the intenet I found similar bugreport from other Linux distrubutions
(https://www.reddit.com/r/kde/comments/i94khf/suddenly_missing_switch_user_button/).

I seems there is a bug report in upstream: https://bugs.kde.org/show_bug.cgi?id=423526
