Comment # 22 on bug 1156501 from Dr. Werner Fink

Beside this on the local console (not X11 but /dev/tty1):

  printenv | grep -E 'XDG_(CURRENT|SESSION)'
  XDG_SESSION_ID=66
  XDG_SESSION_TYPE=tty
  XDG_SESSION_CLASS=user
  secret-tool lookup imaps gwmail.nue.novell.com
  secret-tool: Cannot autolaunch D-Bus without X11 $DISPLAY
  tty
  /dev/tty1

even on the local system a user is not able to use dbus without X11
