see QAbstractItemView::setModel(QAbstractItemModel *model)

    // These asserts do basic sanity checking of the model
    Q_ASSERT_X(d->model->index(0,0) == d->model->index(0,0),
               "QAbstractItemView::setModel",
               "A model should return the exact same index "
               "(including its internal id/pointer) when asked for it
twice in a row.");
