Desktop: Plasma 5.4.3 as shipped with openSUSE Leap

Yesterday I gave a presentation and used a second screen for this. That causes various problems:
- Although the Laptop screen was defined as primary screen, the application bar (kicker) appeared only on the second screen. Trying to change this did not help
- Obviously the the window manager crashed, as the window decoration was gone suddenly (tried the change the output mode with Fn-F7 as well)
- decoupled the second screen -> kicker did not come back
- logged out and in again to get Window Manager working
- kicker became only visible after the second screen was plugged in again
- Used Fn-F7 to have same output on both screens....so I survived the presentation.
Anyway....
- as soon as 2nd screen unplugged, kicker was gone again
- On the KDE configuration panel, the tab to set monitor resolution etc was gone
- after log-off, I could not log in anymore with this user - KDE session hung during startup
- removed everything from the user home directory that looked like temporary stuff (esp ~/.config/session), /tmp, /var/tmp ) and rebooted
- could log in again with the user
- new kicker panel had to be added nevertheless

Reproducible: Always
