Launch the attached application which includes a graphics view with a scene & QGraphicsRectItem.
QGraphicsRectItem is selectable.
After the application has been launched resize the view a bit larger and click on the left side or on the top of the QGraphicsRectItem (i.e. outside of the QGraphicsRectItem).
--> error: QGraphicsRectItem is selected even if user has clicked outside of the QGraphicsRectItem.
This error is a regression from SHA ID 7c0d15a22266a425c9e9ac0120d6774e120fe01e (included into Qt4.7.1).
