404 errors caused by xml-rpc calls are masked

[netchan]

When trying to access a nonexistent object/method, lib/python/ZPublisher/xmlrpc.py sets the status code 200 and sends back a regular xml-rpc Fault, with the standard 'Cannot locate object' message in html format as the body of the Fault.
The attached patch solves the problem if the variable 't' in method 'exception' is a zException.NotFound. Additional check for t=='NotFound' might be necessarry.

The patch is missing the following line:

from zExceptions import NotFound

Also note that apparently the xmlrpc specs tell us **not** to return a 404. The problems is that some spammers who try to abuse xmlrpc won't get it when we don't return a 404, so for the moment I've applied the patch to my own server.

We won't be applying the spec-violating patch.
