Ah, thanks for the clarification. For Yelp 3, I'm not
particularly worried about GConf compatibility, but I
do want it to work outside of GNOME. So I'd like it to
use the keyfile backend if GNOME (or something else)
isn't providing a backend.

Is this the sane thing to do then?

if (g_getenv ("GSETTINGS_BACKEND"))
  settings = g_settings_new ("org.gnome.yelp");
else {
  g_settings_backend_setup_keyfile ("blah", filename);
  settings = g_settings_new_with_context ("org.gnome.yelp", "blah");
}
