Steps to reproduce in 5.13.4: 1. Create a new file on the desktop 2. Delete the file 3. Right-click and select "Undo: Trash" 4. The message "Internal error in copyOrMove, should never happen" appears and the the file will _not_ be restored. Expected: No error message and the file will be restored. I first noticed this behavior in version 5.13.1.
