Well, I found a solution.
1. I renamed the /home/[my-username]/.config directory as /.config.old
2. After logout and new login, a new /.config directory is generated.
3. I replaced the old /.config.old/nautilus directory by the newly generated /.config/nautilus
4. /.config erased.
5. /.config.old renamed as /.config again
5. Logout and new login => problem solved.
