XmlListModel stays in Loading status

When source is defined as a file in qrc, the XmlListModel Status stays in Loading and never become Ready.

Using the xml property with the xml content produce the same behaviour.

Is it because the XmlListModel depends of QThread for asynchronous loading ? 

main.zip attachement provide a simple qml file to reproduce the issue. In console output, the XmlListModel Status stays in Loading.
