Crash only happens when the shape is inserted with the single click method, by Ctrl-clicking on the toolbar button.
- Start a new document.
- Add a shape by Ctrl-clicking on the basic shape icon on the toolbar.
- Press undo until there are no more undo steps (takes 2 undos for some reason).
- Click on the basic shape icon on the toolbar (this just unselects the button).
