How do i bind Class to QML window in Qt5 or is it a bug.

[1roo]

Hi

I create a QML window with
@void Check::createWindow(){
QDeclarativeView *decView= new QDeclarativeView();

    QObject::connect(decView->engine(), SIGNAL(quit()),decView, SLOT(deleteLater()));

    QString mUrl="http://www.google.com";
    decView->engine()->rootContext()->setContextProperty("MyApp",this);
    decView->engine()->rootContext()->setContextProperty("mUrl",mUrl);
    decView->setSource(QUrl("qrc:/inc/getwebsite.qml"));
   decView->show();

}@

my slot (public slot)
@QString Check::getAndBlockSiteToCheck(){

qDebug()<<"Getting site to check";
return QString("http://www.asdf.com");

}@

and qml file
@ import QtQuick 1.1
import QtWebKit 1.0
WebView {

    width:600
    height:700
    settings.javascriptEnabled: true
    settings.javascriptCanOpenWindows: true
    settings.developerExtrasEnabled : true
    settings.autoLoadImages: false


    javaScriptWindowObjects: QtObject {
             WebView.windowObjectName: "MyCom"

             function openNew(){
                      alert('old url '+webView.url);
                      var nexturl=MyApp.getAndBlockBlogToCheck();
                     alert("next url is "+nexturl);
                 webView.url=nexturl;


            }
         }



    id: webView
    objectName: "myWebView"
     url:mUrl


    onLoadFinished: {webView.evaluateJavaScript("window.setTimeout('window.MyCom.openNew()',5000);");}
    onAlert: console.log(message);

}@

It runs first website (google.com) but when it tries to go to new page i get "exited with code -1073741819" error.
I just installed newest Qt5 final.
Where do i make mistake?

I was opening Check::createWindow() from another class without making instance of "Check".
