Error opening security policy file

[Marco <marco4ever@libero.it>]

Hi all,
I have install Debian Etch on my notebook.

When I start X I have this error message:

"error opening security policy file /etc/X11/xserver/SecurityPolicy"

I don't have "SecurityPolicy" file in my system.
#updatedb
#locate SecurityPolicy
(nothing)

I don't have the xserver folder in my /etc/X11/ folder.

What is the SecurityPolicy file?
Could you help me to fix this error message?

Thanks
Bye
Marco
