Crashed when moving Measurement;

[renkehub]

When I select multi Measurement items then move these item, the program crashed!

it seems the function "moveCoordinatesBy" has a bug:
forget adding "prepareGeometryChange"

void QtAnnotation::moveCoordinatesBy(const Point& moveBy) {
// should add prepareGeometryChange ;
std::vector coords = _annotation->getCoordinates();
for (std::vector::iterator it = coords.begin(); it != coords.end(); ++it) {
it->setX(it->getX() + moveBy.getX() / _scale);
it->setY(it->getY() + moveBy.getY() / _scale);
}
_annotation->setCoordinates(coords);
this->setPos(QPointF(coords[0].getX()_scale, coords[0].getY()_scale));
onAnnotationChanged();
emit annotationChanged(this);
}

void QtAnnotation::onAnnotationChanged() {
return;
}
