Active object leave: -14

Hello all,
I have a problem with "QML Video element":http://doc.qt.nokia.com/qtmobility/qml-video.html

My application is developed for Symbian (I use Qt Quick components). I use "pageStack":http://doc.qt.nokia.com/qt-components-symbian/qml-pagestack.html system for manipulating with pages.

MainPage.qml
@
import QtQuick 1.1
import com.nokia.symbian 1.1
import QtMultimediaKit 1.1
import Mediakey 1.0
import "Api.js" as Api

Page {
id: mainPage
orientationLock: PageOrientation.LockPortrait

Image {
    source: "images/background.png"
    id: content
    anchors.fill: parent

    Button {
        anchors.top: parent.top
        anchors.topMargin: 10
        anchors.right: parent.right
        anchors.rightMargin: 10
        iconSource: "images/exit.svg"
        onClicked: Qt.quit()
    }

    Flickable {
        id: flick
        width: 360
        height: parent.height - 60
        y: 60
        contentHeight: t1.y + 50
        contentWidth: 360

        Image {
            anchors.horizontalCenter: parent.horizontalCenter
            source: "images/logo.png"
            id: logo
        }

        Button {
            property string url: "http://something.mp4"
            anchors.horizontalCenter: parent.horizontalCenter
            text: "1×01 + 1×02 – Děti bohů"
            x: 20
            anchors.top: logo.bottom
            anchors.topMargin: 20
            id: t1
            onClicked: {Api.loadVideo(url)}
        }
    }

}

function loadVideo(source) {
var component = Qt.createComponent("VideoPage.qml");

    pageStack.push(component, {src: source});

    onVolumeUpPressed: {slider.visible = true; timer2.running = true; slider.value += 0.1}
}
}

So, I open VideoPage (by Button t1). My video loads normally. I close the page (it stops video too). When I try to open the video again Qt Creator throws "Active object (ptr=0x08d056c0, vptr=0x7ed8966c) leave: -14" and I can see on my device "{app name}: Is already used". The page does not open.

Thank you for any help
