    Description

      bool QStandardItemPrivate::insertRows(int row, const QList<QStandardItem*> &items)
{
    Q_Q(QStandardItem);
    if ((row < 0) || (row > rowCount()))
        return false;
    int count = items.count();
    if (model)
        model->d_func()->rowsAboutToBeInserted(q, row, row + count - 1);

      If 'count' is 0 and 'row' is 0, than 'row + count - 1' will -1.
      In this situation QAbstractItemModel::beginInsertRows failed on

      Q_ASSERT(last >= first);
