Christian Ehrlicher 794140fb86 QGraphicsProxyWidget: Don't crash within setWidget() when a child proxy has no assigned widget ... QGraphicsProxyWidget::setWidget() is checking if the newly assigned widget is already assigned to a child proxy widget without checking if the child has a widget assigned at all which lead to a nullptr reference if it is not the case. Therefore check if the assigned widget is a valid pointer.
