same icons for several users

[kevin]

Hello,

As administrator of a debian etch system, I want a group of users to 
have the same icons as those defined for the user named "model.

So I
1/ copied recursively /home/model/.cache/xfce4/
2/ changed every occurence of "model" by <UserName> in
/home/<UserName>/.cache/xfce4/desktop/menu-cache–etc-xdg-xfce4-desktop-menu.xml.fr.rc

As far as I know, icons places and types are defined in 
/home/model/.cache/xfce4/desktop/icons.screen0.rc

And made <UserName> the owner of his .cache subtree.


But it fails, no icon...

Any idea ?

Thanks
