QHeaderView creates persistent indexes in _q_sectionsAboutToBeChanged(), called by the slot connected to rowsAboutToBeMoved/columnsAboutToBeMoved. In the case of rows, QAbstractItemModel emits the signal *before* preparing to update persistent indexes in itemsAboutToBeMoved(), so it can see the ones newly created by QHeaderView, all is well. In the case of columns, the emit was done *after* calling itemsAboutToBeMoved(), so the additional persistent indexes created by QHeaderView were ignored, and in endMoveRows() we could end up with: ASSERT failure in QPersistentModelIndex::~QPersistentModelIndex: "persistent model indexes corrupted" This bug has been there since the very beginning of beginMoveColumns(), but was undetected because moving columns in a model is pretty rare (in my case there's a QTransposeProxyModel that turns columns into rows in the underlying model, and a proxy that handles dropMimeData...)
