Waiting to see if this remove totally the issues.

So feedback after trying this:

• it crash much less:
  Explication: because the patch prevent the exception by overloading the view method, it prevents the exception
  when it comes from SDLSurface View

  But, I also use another view for advertisement, this is one is "final" so I cannot overload the method in this view.
  And probably it still crash when cursor goes into this view.

• it doesn't cause any trouble: no report about issue with this patch.
  I also tested with a Mouse / forcing a cursing and returning null. it doesn't hurt.

So I would merge this PR
