Use of location API crashes the Nokia E71.

Using the location API on the Nokia E71, gives an error message "LBS thread crashed". I basically only request a location update, following the example in the documentation:

QGeoPositionInfoSource *source = QGeoPositionInfoSource::createDefaultSource(this);
if (source)

{ connect(source, SIGNAL(positionUpdated(QGeoPositionInfo)), this, SLOT(positionUpdated(QGeoPositionInfo))); source->startUpdates(); }

(See whole project attached) The code works well in the Nokia QT SDK emulator.
