Since GNOME 3.6, the only screensaver outside fallback mode is that
implemented by gnome-shell, ie the one you activate with
Main.screenShield.lock(true);
gnome-settings-daemon, the component handling keybindings, uses the
DBus interface to communicate the shell, calling
org.gnome.ScreenSaver.Lock, which then triggers the same code path as
the user menu button.
If that doesn't work, you should file a bug at https://bugzilla.gnome.org
