After the last row is moved, 0 will be returned when obtaining row and column data. At this time, QListView::doitemslayout will not call d->doitemslayout, so the QBspTree data structure will not be cleaned up, leaving a stale tree structure behind. This will trigger an assert during paintEvent handling if QListView is set to IconMode In QListView::ListMode the test for a valid model index doesn't use an assert. Call QListViewPrivate::clear explicitly if the column count is 0 so that the QBspTree and other data structures are cleared. Add a test case that simulates this scenario by implementing a model that returns a 0 column count for an index after the model structure was changed through a move of rows.
