No resize event received on screen orientation changed

As mentioned in "CS001437 - Listening for screen orientation changes in Qt" and in "Dynamic Layout handling with QWidget in Qt for Symbian" a resize event is supposed to be fired when screen orientation changes.

This event is not fired (running on my device) on my sample application (see attached source code): displays a label with QResizeEvent data captured in QMainWindow subclass. Application Ui is not rotated landscape when phone is et to this position.
Device sensors are OK: made a test application displaying accelerometer, orientation and rotation sensors values + Nokia Gallery application shows pictures in portrait/landscape according to phone orientation.

Same result with QtEggAlarm application.

The event is fired under Qt Simulator and using Remote device Access (don't know if screen is physically rotated...).
