      Description

      When a ConicalGradient is used in qml on Android, pressing the native Android back button causes the application to crash. This was found in a large project, so I created and attached a small example of this happening, conicalTest.zip.

      The crash is a Segmentation fault and the stack trace in the QtMainThread when it crashes is:

      1 QQuickEventPoint::grabberItem() const 0xdaf75072
      2 QQuickWindowPrivate::removeGrabber(QQuickItem *, bool, bool) 0xdaf8d998
