Description
The crash happens in QtDS new design system view. The code that causes the crash looks like the following. Here the line let result = tableView.model.setData(index, prop, Qt.EditRole) inside the onDestruction handler causes the crash. When this line commented out there is no crash.
The crash happens when going from A to B but not when going from B to A.
