Hi Guys,
I'm trying to run a very basic QtLocation application. It contains only a QGraphicsView widget and I want to add a QGraphicsGeoMap item to this view's scene. The code compiles without errors but when I try to run the app I immediately get a segmentation fault.

Here's the code:
Qt Code: 
  1. ui->setupUi(this);
  2. QGraphicsScene *mapScene = new QGraphicsScene(this);
  3. ui->graphicsView->setScene(mapScene);
  4. ui->graphicsView->setInteractive(true);
  5.  
  6. QGeoServiceProvider serviceProvider("nokia");
  7. QGeoMappingManager *manager = serviceProvider.mappingManager();
  8. QGraphicsGeoMap *geoMap = new QGraphicsGeoMap(manager);
  9. ui->graphicsView->scene()->addItem(geoMap);

Here's the error:
Qt Code:

I'm running Qt 4.7.1, QtMobility 1.1.0 and QtCreator 2.0.1 under Win 7.
I'd really appreciate any ideas how to solve this problem.
