Hi,
I am facing an issue when, in QGraphicsScene using BSPItemIndex method, I try and delete a QGraphicsItem at some specific positions only.
The application simply crashes and when tried debugging goes to QGraphicsScene::qt_metacall(..).

If I change the ItemIndexMethod to NoIndex the application works correctly.

The application requires a large dynamic scene, hence using NoIndex makes the application considerably slow.
Is changing the ItemIndexMethod run-time advisable ?
Please provide some pointers to the issue.
