QT调用opencv的imshow函数后异常退出

int main(int argc, char *argv[])
{
   QApplication a(argc, argv);
    MainWindow w;
    w.show();
    Mat image = imread("/home/milk/number/img_1.jpg",0);//Mat(hight1,width1,CV_8UC1);//.clone();
    imshow("suoxiao1",image);
    waitKey(0);
    return a.exec();
}

这是主函数，如果把 QApplication a(argc, argv);及其相关注释调，单独运行opencv的程序没有问题，如果加上qt的窗口控件，就会异常退出，经过排查就只有在运行imshow函数的时候才会异常退出，pro文件配置如下，问题会是什么呢？
