      Description

      The following example code will crash when requesting QPrinter::printerName() after setting paperName with QPrinter::setPaperName().

      Crash only occurs on 10.8, 10.7 is working fine.

      main.cpp
      #include "mainwindow.h"
      #include <QApplication>
      
      #include <QPrinter>
      #include <QPrinterInfo>
      
      int main(int argc, char *argv[])
      {
          QApplication a(argc, argv);
          MainWindow w;
          w.show();
          QPrinter * printer = new QPrinter();
          QPrinterInfo pInfo(*printer);
          QList<QPair<QString, QSizeF> > papers = pInfo.supportedSizesWithNames();
          if(papers.size() != 0){
              //Calling setPaperName causes us to crash comment this line out and it works.
              //This works on OSX 10.7 Crashes on OSX 10.8.
              printer->setPaperName(papers.begin()->first);
              w.setWindowTitle(papers.begin()->first);
          }
      
          QString pName = printer->printerName();
          printer->setPrinterName(pName);
      
          return a.exec();
      }
