could you please add debug statement in QWidgetPrivate::create_sys to 
check argv and argc values?
something like:
         qDebug() << "argc:" << qApp->d_func()->argc << "; argv:" << 
qApp->d_func()->argv;
         for (int i = 0; i < qApp->d_func()->argc; ++i)
             qDebug() << "argv[" << i << "]:" << qApp->d_func()->argv[i];

Do you run your application with some specific command-line arguments?
