QMediaPlayer buffer underrun?, streaming not working properly

QMediaPlayer doesn't work properly when doing streaming. Usually songs get interrupted in the middle, around 2:15 minute. When debugging my app, I got "ResourceError" and Symbian -36 error, however the state is always QMediaPlayer::BufferedMedia and the position goes to the end.

My testing code http://pastebin.com/RkWp58Xk

My code in short:

myPlayer = new QMediaPlayer(this, QMediaPlayer::StreamPlayback);
myPlayer->setVolume(100);
myPlayer->setMedia(QUrl("http://mydomain.com/test.mp3"));
myPlayer->play();

The songs play very well, however they always get interrupted in the middle. I tried with different servers, songs and sizes and the same happens.

What could be the problem when doing streaming with QMediaPlayer? Is it a buffer problem? If so, how can I increase the buffer size? There is no method in QMediaPlayer to set the buffer size. I tried the QML Audio element and I got exactly the same results.

My phone is the N8 with Qt 4.7.4 and QtMobility 1.2.1 and this is included in my .pro file:
QT += network

symbian {
TARGET.CAPABILITY += NetworkServices ReadDeviceData ReadUserData WriteDeviceData WriteUserData
TARGET.EPOCHEAPSIZE = 0x400000 0x8000000
TARGET.UID3 = 0x20065759
...
...
}

CONFIG += mobility
MOBILITY += multimedia

Could you please give some direction on how to solve this?
