QWebpage always return false for signal loadfinished

Hi

I am trying to use QWebPage class and loadurl function to load an webpage. I always get load finished signal as false. Here is my code

m_page -> mainFrame() -> load(QUrl("http://www.google.com"));
view->setPage(m_page);
QVERIFY(view->page() == m_page);
view->showMaximized();

I tested my proxy settings and it works fine if i use QWebView class and load(QUrl("http://www.google.com)).
