That is the loop back IP address.  IIUC, the IP address for your system
is defined as 127.0.0.0.  I don't know if you can use an IP address
there.  It says Host/Domain. but the IP address might be acceptable.

The Help file isn't much help here.  It says:

Not very helpful, and clearly it there is an error since it confuses 
'host' and domain.  Should a bug report be filed for this?

I also wonder about:

	Host/Domain

This is possibly confusing since it is actually:

	Host.Domain

So, what I don't know and the empty documentation doesn't say is 
whether: "localhost" is sufficient or if "localhost.localdomain" is 
necessary and whether the local IP address (127.0.0.0) would also work. 
  I presume that an IP address should work since not all websites have a 
Host.Domain URL.

So, if you have:

	localhost		Accept

does it work, and are you sure that you didn't name your system
something else?  Some distros encourage you to name your system --
something that I don't think is a good idea (some things appear to 
presume that your system is "localhost.localdomain" even if you try to 
name it something else).

Look for a file named:

	/etc/hostname
	/etc/HOSTNAME

and see what it says.  If there is something other than "localhost" in 
the file then you need to use that.

Then you could try:

	localhost.localdomain	Accept

{or substitute your HostMame for "localhost" if it is different}

There is a lot of code for Konqueror, but it is modular.  The JavaScript
code is actually in "kdelibs/khtml/ecma/.  ECMA Script is the correct
name for JavaScript.  I don't know exactly where the JavaScript policy 
is controlled.
