Comment 87 for bug 1244090

Maybe report confused with unity-settings-daemon (fork of gnome-settings-daemon in Ubuntu)? Original gnome-settings-daemon does not have code (in media-keys plugin) to switch keyboard layouts:

                  break;
          case BATTERY_KEY:
                  do_battery_action (manager);
                  break;
+ case SWITCH_INPUT_SOURCE_KEY:
+ case SWITCH_INPUT_SOURCE_BACKWARD_KEY:
+ do_switch_input_source_action (manager, type);
+ break;
          /* Note, no default so compiler catches missing keys */
          case CUSTOM_KEY:
                  g_assert_not_reached ();
