Qt Safelayout fails to parse RPMFIipably.qml in qtcluster

SafeLayout tool fails to parse the following QML

    front: Loader {
        id: rpm
        width: parent.width
        height: width
        asynchronous: true
        source: "RPMGauge_painter.qml"
        onLoaded: flipable.loaded()
    }

C:/Users/teholapp/workspace/qtsaferenderer/examples/saferenderer/qtcluster/qml/dash_sports/RPMFlipable.qml:68: error: the property value is not a number. 

Parsing of the parent.width works but width property parsing fails.
