gnome-screensaver does not install a DBUS service definitiion file

Binary package hint: gnome-screensaver

In karmic's GNOME desktop, locking the screen is accomplished through D-BUS by using the Lock method provided by gnome-screensaver. However, the package installs no service file so D-BUS calls don't work.

Initially I was not able to lock the screen using the indicator-session-applet "Lock Screen" menu item, Ctrl-Alt-L, or sending the D-BUS command manually. After creating and customizing the file /usr/share/d-bus1/services/org.gnome.ScreenSaver.service (attached), the latter two methods began working immediately, and the menu item began working after a reboot.
