Comment 1 for bug 1390643

Adding gsettings-qt for another pair of eyes because at first glance the u-s-s code looks alright:

http://bazaar.launchpad.net/~system-settings-touch/ubuntu-system-settings/rtm-14.09/view/head:/plugins/orientation-lock/EntryComponent.qml?start_revid=935

    control: Switch {
        id: control
        objectName: "orientationLockSwitch"
        checked: systemSettings.rotationLock
        onClicked: {
            systemSettings.rotationLock = checked
        }
        GSettings {
            id: systemSettings
            schema.id: "com.ubuntu.touch.system"
        }
    }
