    Description

      Open pro file from qtdemo/qmediaplayer pro file, changing class mediaplayer : public QWidget to public QMainwindow.
      Recompile and start causes a deadlock. (no window appears, deadlock in qeventhandler)

      (seems like hanging somewhere in quarz / evr / directshow filter renderer waiting for a mediasample) qt gui thread waits in qeventdispatcher)

      Mediaplayer derived from qwidget works well.
      Reproducable, no change to start without deadlock.
