only one text line after showing text in QgraphicsSvgItem

I think there is a bug in QgraphicsSvgItem. I created a svg file with text. There 3 lines are shown but after adding this file to QGraphicsScene you only can see one line. So I think this is an Bug of QgraphicsSvgItem.

QGraphicsSvgItem *image_item;

      image_item = new QGraphicsSvgItem("/text.svg");
      image_item->setPos(300, 300);
