Qmlscene leaking memory on simple qml file

[sdrsdr]

HI All,
I got this simple qml file and qmlsceen is leaking memory while the image is bouncing around. This is on windows 64bit OpenGL installed from qt-opensource-windows-x86-1.5.0-2-online.exe

the qml is:

@import QtQuick 2.0

Rectangle {
width: 360
height: 360
Text {
text: qsTr("Hello World")
anchors.centerIn: parent
}
MouseArea {
anchors.fill: parent
onClicked: {
Qt.quit();
}
}

Image {
    id: image1
    x: 8
    y: 8
    width: 45
    height: 39
    visible: true
    source: "qq_pl80.png"
    PropertyAnimation on x {
         to:320;
         duration:5000;
         easing.type: Easing.OutBounce;
         onStopped: {
             if (to===320) to=8;
             else {
                 to=320;
                 gc();
             }
             start();
         }
    }
}

}
@

Am I doing something wrong or this is "per design"? Shall I file a bug report?
