OK, I've done a little more investigation to see how the crash is triggered.
1) Create a new menu.
2) Drag a shortcut from the desktop into the new menu.

But...
1) Create a new folder.
2) Drag a shortcut from the desktop to a previously existing menu.
3) Drag the shortcut from the existing menu to the new menu.
