I see. I thought to try it with sysvinit as well, but did not yet do it.

Is running as root here.

krunner is also running when it is not shown, so that could be a work 
around.

The keyboard? Well krunner has runit as parent process. But does that 
have to do with a keyboard? You mean it could be an issue with elogind?

What would you suggest to find out?

Another thing that comes to my mind is: Plasma a systemd startup method 
meanwhile, but can also work without systemd¹. Maybe the issue is 
related to using a different code path in Plasma for non-system startup? 
Ah, why didn't I think of this earlier. I just searched KDE bugzilla and 
got this:

krunner starts applications with cwd "/" with init system other than 
systemd (openrc, runit, ...)

https://bugs.kde.org/432975

So it appears to be upstream breakage?

Indeed. Also the file dialog for example in kwrite / kate or okular would 
start out in "/" in that case.
