Bug#431088: exim4-config: Crashes on upgrade

[John Goerzen]

Package: exim4-config
Version: 4.67-5
Severity: important

In my /etc/exim4/update-exim4.conf.conf, I have this (hostnames changed
for this report):

dc_smarthost='"${if eq {LOCATION}{home}{host1.example.com}{host2.example.com}}"'

Upon trying to dpkg --configure -a, this package crashes with:

Setting up exim4-config (4.67-5) ...
/usr/sbin/update-exim4.conf: non-ascii value "${if eq {location}{home}{host1.example.com}{host2.example.com}}" read from /etc/exim4/update-exim4.conf.conf, sanitizing to ___if eq _location__home__host1.example.com__host2.example.com___
2007-06-29 10:41:57 Exim configuration error in line 722 of /var/lib/exim4/config.autogenerated.tmp:
  option "DEBCONFheaders_rewriteDEBCONF" unknown
Invalid new configfile /var/lib/exim4/config.autogenerated.tmp, not installing
/var/lib/exim4/config.autogenerated.tmp to /var/lib/exim4/config.autogenerated
dpkg: error processing exim4-config (--configure):
 subprocess post-installation script returned error exit status 1

The headers_rewrite appears to be a separate problem related to the fact that
I did not take upgrades to 30_exim4-config_remote_smtp_smarthost, which
would have broken some custom configs.
