drag and scroll crash

[eboudrant]

When I start dragging an item to the end of the list it scroll the gridview, at one point it crash with :

E/AndroidRuntime(16580): java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.ViewParent android.view.View.getParent()' on a null object reference
