Bug 432512

I just noticed this behaviour after switching over to the experimental systemd plasmashell startup. The daemon keeps restarting itself and the following can be seen in journalctl (mind the reversed order).

The problem went away after disabling systemd startup. I can try to gather more debugging data but I'd appreciate a few hints what to look for. I run up-to-date Arch Linux with Plasma 5.20.90 beta.
