Bug#430391: exim4-config: Phantom "non-ascii characters" in update-exim4.conf.conf

[Lee Cremeans]

Package: exim4-config
Version: 4.67-4
Severity: important

I just did an upgrade on my Debian unstable system, and now I'm getting this message from update-exim4.conf:

/usr/sbin/update-exim4.conf: non-ascii value <; 192.168.0.0/24;192.168.1.0/24 read from /etc/exim4/update-exim4.conf.conf, sanitizing to _; 
192.168.0.0/24;192.168.1.0/24
/usr/sbin/update-exim4.conf: non-ascii value <; 127.0.0.1;192.168.0.1;192.168.1.1 read from /etc/exim4/update-exim4.conf.conf, sanitizing to _; 
127.0.0.1;192.168.0.1;192.168.1.1

This is keeping exim4's other packages from configuring. If I blank the fields in question, exim4-config no longer complains, but I use the fields to make 
email work from my other machines.
