I'm not sure about the nomenclature. Here's what I did (gets called when
clicking on the calendar "widget"):
#v+
(dbus-register-method :session
"org.gnome.Shell.CalendarServer"
"/org/gnome/Shell/CalendarServer"
"org.gnome.Shell.CalendarServer"
"GetEvents"
'ogc:--dbus-get-events)
#v-

Bad paste, sorry. This is the back trace:
#v+
Debugger entered--Lisp error: (wrong-type-argument D-Bus nil)
dbus-message-internal(2 :session ":1.15" 18386 ("" "Test" "" nil 63490176000
63490176001))
apply(dbus-message-internal 2 :session ":1.15" 18386 ("" "Test" "" nil
63490176000 63490176001))
dbus-method-return-internal(:session ":1.15" 18386 ("" "Test" "" nil
63490176000 63490176001))
apply(dbus-method-return-internal :session ":1.15" 18386 ("" "Test" "" nil
63490176000 63490176001))
#v-
And here's a test handler:
#v+
(defun ogc:--dbus-get-events (since until force-reload)
'(("" "Test" "" nil 63490176000 63490176001)))
#v-

Adding a ":int64" also throws an error.

Does not seem to exist in my currently installed package... (latest jd's
emacs-snapshot).
