      {
      QApplication app(argc, argv);
      /*
      Given "s" without a leading emtpy paragraph works correctly. Here is the output:
      */

      QString s = "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0//EN\" \"http://www.w3.org/TR/REC-html40/strict.dtd\"> "
      "<html><head><meta name=\"qrichtext\" content=\"1\" /><style type=\"text/css\"> "
      "p, li

      { white-space: pre-wrap; }

      "
      "</style></head><body style=\" font-family:'Arial'; font-size:56pt; font-weight:400; font-style:normal;\"> "

      t.setHtml(s);
      qDebug() << "--- end raw string output ---";
      qDebug() ;
      qDebug() << t.toHtml();
      qDebug() ;
      /*
