cursor problem with qwebview inside a widget added to a qgraphicsscene

Hello, I have a small, but important issue with qwebview cursor, that is not changed to hand when mouse is over a link.
I have a qgraphicsscene where I place several widgets like clocks, comic book reader and one is a widget with a layout that contains a single qwebview. It works fine, except that the mouse cursor do not change over links (it actually changes sometimes, for less than a second, but changes back to arrow).

Does anyone knows anything about this or a solution?

Using Qt 4.6.2.
