Comment # 30 on bug 1156501 from Dr. Werner Fink

Found the culprit ... it was a leftover of a test for dbus-broker now two years
back:


 ll /etc/systemd/user/dbus.service
 lrwxrwxrwx 1 root root 41 Oct 10  2018 /etc/systemd/user/dbus.service ->
/usr/lib/systemd/user/dbus-broker.service

and  /usr/lib/systemd/user/dbus-broker.service had not exist anmymore after the
zypper dup.  And new systemd had not ignored the broken link but marked the
dbus.service as not loaded (but without hinting why it has not loaded).

After removing the dangling symlink and reboot (as a simple daemon-reload had
not helpd out), things are now working ... OK I had also removed the
crediential lines from my ~/.oscrc so that it use the gnome-keyring (btw. the
error message of kwalletd5 still remains with the not existing SmartCard).
