This was a very bad call and breaks Apache/mod_rpaf for those of us that use Apache 2.2 on Ubuntu 12.04, where the configuration directives are, as per the documentation of libapache2-mod-rpaf, like this (from /usr/share/doc/libapache2-mod-rpaf/README):

RPAFenable On
# Enable reverse proxy add forward
RPAFproxy_ips 127.0.0.1 10.0.0.1
# which ips are forwarding requests to us
RPAFsethostname On
# let rpaf update vhost settings 
# allows to have the same hostnames as in the "real"
# configuration for the forwarding Apache
RPAFheader X-Forwarded-For
# Allows you to change which header mod_rpaf looks
# for when trying to find the ip the that is forwarding
# our requests
