Memory Leak Observed in qwebpage.

I am going through the code of qwebpage.cpp I found the below code
void QWebPage::setView(QWidget* view)
{
    if (this->view() == view)
        return;

    d->view = view;
    setViewportSize(view ? view->size() : QSize(0, 0));

    // If we have no client, we install a special client delegating
    // the responsibility to the QWidget. This is the code path
    // handling a.o. the "legacy" QWebView.
    //
    // If such a special delegate already exist, we substitute the view.

    if (d->client) {
        if (d->client->isQWidgetClient())
            static_cast<PageClientQWidget*>(d->client)->view = view;
        return;
    }

    if (view)
        d->client = new PageClientQWidget(view);
}

Here d->client is created but it is not deleted.

I have QtWebkit build on S60(Symbian) environment. 
I found this as a leak using hook logger while executing unit testcases.

client is a OwnPtr, your tool is broken or the code has been updated since you reported the issue.
