Seek in QML Audio after stop

I try to execute example Quick Player. When playback is completed(status - stopped), i set position slider to the free value and record start to play from this point without changing playbackState and position properties.
I make small changes to illustarte my problem.
main.qml:

MediaPlayer {
...
onPlaybackStateChanged: {
print("State:" + playbackState);
}
onPositionChanged:{
print ("Pos:" + position);
}
}

And that's what i've got:

State:1 // Start playback
Pos:700
Pos:1714
Pos:2728
Pos:3742
Pos:4756
Pos:5770
Pos:6784
Pos:7517
State:0 // Stop playback
Pos:1500 // Seek
Pos:7517 // Stop playback
Pos:756 // Seek
Pos:7517 // Stop playback
Pos:1576 // Seek
Pos:7517 // Stop playback

I really hope you will fix this error as fast as it can be. I need your help at this situation very much. Otherwise our startup will fail.
