Application crashes with QGraphicsView + setAcceptHover

Hello!

I think I discovered a bug.

What I'm doing:
I add a custom QGraphicsItem subclass to the scene, which does setAcceptHover(true);

In the hoverMove event, I add another QGraphicsView to the scene.
In the hoverLeave event, I remove it again.

If I don't set setAcceptHover(false) on the item I add in hoverMove, the app will crash as soon as the mouse cursor hovers over the new item.

I attached a simple test project.
