Qt Webkit crash visiting a specified website

Hi!

Using Qt 5.1.1 I created a simple application with a QWebView (a MainWindow, layoutmanager and a QWebView).

After loading a specified website AND using the arrows of the banner if I use the vertical scrollbar I get a segmentation fault.

Debugging the code I get this message:

ASSERTION FAILED: m_outlineBox == renderer()>outlineBoundsForRepaint(renderer()>containerForRepaint(), geometryMap)
rendering\RenderLayer.cpp(554) : void WebCore::RenderLayer::updateLayerPositionsAfterScroll(WebCore::RenderGeometryMap*, WebCore::RenderLayer::UpdateLayerPositionsAfterScrollFlags)

I am not sure if I might post the URL of the website, because I don’t want to advertise it, but you can reproduce the problem knowing it.

I checked it with firefox and it is working fine.
I attached the source code and picture from the segmentation fault.

I suspect that the JavaScript causes the problem, therefore workaround the problem I disable the JS after loading the main webpage and enable it in every other case.
