This is for Tumbleweed 20180225, but there was a time a week or so ago when I
got something similar, that was fixed by a later update. Journalctl shows
some stuff new to me also. I don't recall seeing activity manager mentioned
before, but gnome keyring has been mentioned for a long time without apparent
consequences. Later attempts skip the activity manager part.
