play mediaplayer a while, then pause it more than 10 seconds or longer. the mediaplayer status will change to LoadingMedia and StalledMedia, and it's position will change to 0.

Use QMediaPlayer to play internet mp3, when start to play, the QMmediaPlay's MediaStatus changed from: LoadingMedia->BufferedMedia, then begin to play. sometimes the network is not very well, the MediaStatus change to StalledMedia->BufferedMedia. everything is fine, except pause the mediaplayer a long time(more than 10 seconds or longer). when do it, QMediaPlayer's MediaStatus will change to LoadingMedia->StalledMedia->LoadingMedia->StalledMedia.......until to InvalidMedia. The QMediaplayer position change to 0 at this time. but not always like this, sometimes lucky, after LoadingMedia->StalledMedia, it change to BufferedMedia.
But we test it in simulator, don't happen.
And I have test it in four N950 devices. one of them which version is "1.2011.34-2_PR_RM680" don't happen these bugs, the others which version are "3.2012.02-6_PR_RM680" will. I am confused, the lower version doesn't have bugs with it, but higher does.
