updateTimeout() is not emitted if update interval is set exactly to the minimum value

Code:
m_highInfoSource = QGeoPositionInfoSource::createDefaultSource(this);
m_highInfoSource->setPreferredPositioningMethods(QGeoPositionInfoSource::SatellitePositioningMethods);
int highMinUpdateInterval = m_highInfoSource->minimumUpdateInterval(); // returns 1000
m_highInfoSource->setUpdateInterval(highMinUpdateInterval);
connect(m_highInfoSource, SIGNAL(positionUpdated(QGeoPositionInfo)), this, SLOT(highAccuracyPositionUpdated(QGeoPositionInfo)));
connect(m_highInfoSource, SIGNAL(updateTimeout()), this, SLOT(highAccuracyUpdateTimeout()));

Result:
highAccuracyUpdateTimeout() is never called

Workaround:
Increase highMinUpdateInterval for at least 1 millisecond.
m_highInfoSource->setUpdateInterval(highMinUpdateInterval + 1); // should do the trick
