PositionSource.update() (QML method) does not work in Harmattan

examples/declarative-location/flickr Qt Mobility example application does not work in the Harmattan. Same application works ok in Symbian(Belle). Problem is PositionSource.update() method. For some reason, it does not get location information.

Application starts to work if it is changed so that it uses PositionSource.start() and PositionSource.stop() method but as mentioned, root cause is that PositionSource.update() method is not work. Modified code attached(GeoTab.qml).
