QML Video element is crashed when the application is swiped on the dash board on Nokia N950

I tried to use qml video control from QtMultimediaKit but it works very unstable.
1. It crashed when the app swiped on the dash board.
2. In case of using RTSP video stream it writes into log very often "Could not read from resource" but doens't send any events to the application. At the same time another players (on Desktop or Maemo N900 GStreamer) works fine and don't have any troubles with playing the same streams in the same conditions.

Also I tested QMediaPlayer/QVideoWidget from Qt/Mobility component (without using QML) it worked a little better than the QML player.

Please find in attacment files a little demo project for this issue. It uses our rtsp stream to play.
