Using GMemorySettingsBackend before any other GSettingsBackend would cause the following error: "Tried to implement non-registered extension point gsettings-backend". This is due to a missing call to _g_io_modules_ensure_extension_points_registered() in the GMemorySettingsBackend type definition which registers the gsettings-backend extension point.
