FTR, this is the content of the corresponding .desktop file /usr/share/kservices5/YaST-systemsettings.desktop (openSUSE-specific):

Comment 3 Wolfgang Bauer 2020-05-20 11:35:06 UTC 
It's apparently caused by this commit in kcmutils:
https://commits.kde.org/kcmutils/6aa21a42ea6a49d425d40e017ac20d0a5a4abec7

If I revert it, the YaST systemsettings entry works fine.
Comment 4 Rik Mills 2020-05-20 17:39:13 UTC 
The same crash can been seen in Kubuntu when trying to launch the external software-properties app (driver manager) via systemsettings.
Comment 5 Wolfgang Bauer 2020-05-20 19:15:50 UTC 
It crashes in KCModuleInfo::service() because d->pluginInfo is not valid.

Avoiding the crash would be easy by adding a check for d->pluginInfo.isValid() there, but launching external applications would still not work as they are not really plugins (and the mentioned commit basically removes support for that).

Btw, launching external apps from systemsettings is somewhat "documented" in https://invent.kde.org/plasma/systemsettings/-/blob/master/examples/external-application.txt (by using "X-KDE-ServiceTypes=SystemSettingsExternalApp", systemsettings does install a corresponding kservicetypes file too), so a KF5 update probably shouldn't break that IMHO.

The Kubuntu one does set X-KDE-ServiceTypes=SystemSettingsExternalApp, but it still crashes.

Sure (like openSUSE's YaST), that's exactly what broke by that commit.

You might have misunderstood me though. I wanted to say that a KF5 update is probably not supposed to break that IMHO.

I think I did, and agree.

Git commit 0f442313d3357ef5d3cf1d3419944660d49d146d by David Faure.
Committed on 20/05/2020 at 20:50.

Fix crash when loading an external app KCM like yast

This re-instates the use of KService as a first-class citizen
in KCModuleInfo, apparently needed for non-plugins.

A unittest ensures that the very basic use of service() on such
a desktop file doesn't crash.

My apologies for this regression. I had no idea such "fake" KCMs existed.

Thank you!
I can confirm that it fixes the problem here, YaST starts now again as before.
