Qt5.0.1 下QImage 或者QPix地图的load方法都失效啊 4.8下没有关问题啊 大侠们 知道为啥

  QPixmap lpmap("/home/merlin/13.png");


//        lpmap.load(path);



        QListWidgetItem *pItem = new QListWidgetItem(QIcon(lpmap),persionIndex+" "+time.replace("-",":"));

        path = Global::DEFAULT_ENTYR_BACKUP_FOLDER+fileInfo.fileName();

        pItem->setSizeHint(QSize(110,110));

        if(Global::isFileExits(path))

        {

            ui->listExit->addItem(pItem);

        }

        QListWidgetItem * pItem2 = new QListWidgetItem(QIcon(lpmap),persionIndex+" "+time.replace("-",":"));

        pItem2->setSizeHint(QSize(110,110));

        ui->listEntry->addItem(pItem2);
