Desktop Icons with Wrong Sizes and Positioning

[Leandro R]

According to what I read, Nautilus is responsible for managing the desktop, but in Ubuntu 9.10 Netbook Remix Menus and Icons look diferent, so I am not sure if Nautilus is the cause of the bug.
My Nautilus version is:
leandro@leandro-laptop:~$ apt-cache policy nautilus
nautilus:
  Instalados: 1:2.28.1-0ubuntu3
  Candidato: 1:2.28.1-0ubuntu3
  Tabla de versión:
 *** 1:2.28.1-0ubuntu3 0
        500 http://archive.ubuntu.com karmic-updates/main Packages
        100 /var/lib/dpkg/status
     1:2.28.1-0ubuntu1 0
        500 http://archive.ubuntu.com karmic/main Packages

The problem happens under Sistema (System) -> Preferencias (Preferences).
The icons of the third row are too long and they push the icons of the fourth row under the ones of the following catergory: Administración (Administration).
I am attaching a screenshot of the problem that shows how the icons are showed underneeth the ones of the Administration Category, and will try to upload also a picture of the Preferences categories as well
