Comment # 20 on bug 1156501 from Dr. Werner Fink

I should mention that dbus-launch requires X11 $DISPLAY ... and I really like
to know *Why* a dbus launch depend on X11 screen?  With ssh

  secret-tool lookup imaps gwmail.nue.novell.com
  secret-tool: Cannot autolaunch D-Bus without X11 $DISPLAY

btw forwarding the X11 display

  secret-tool lookup imaps gwmail.nue.novell.com
  secret-tool: Error calling StartServiceByName for org.freedesktop.secrets:
Timeout was reached

Clear as the remote DISPLAY does not provide services on the actual system.

Using dbus-run-session with ssh:

 exec dbus-run-session -- /bin/tcsh -l
 secret-tool lookup imaps gwmail.nue.novell.com
 dbus-daemon[17204]: [session uid=223 pid=17204] Activating service
name='org.freedesktop.secrets' requested by ':1.0' (uid=223 pid=17225
comm="secret-tool lookup imaps gwmail.nue.novell.com ")
 gnome-keyring-daemon: insufficient process capabilities, insecure memory might
get used
 secret-tool: Error calling StartServiceByName for org.freedesktop.secrets:

... actual no way to work from at home on the current Tumbleweed
