Thanks for submitting this bug. The upgrade log shows:

2012-08-26 19:42:24 Exim configuration error in line 22 of /var/lib/exim4/config.autogenerated.tmp:
  main option "av_scanner" unknown

Could you please post your /var/lib/exm4/config file (sanitized if need be)?

Hello Serge,
I'm attaching two files for the exim4 installation file, one the
config.autogenerated and the config.autogenerated.tmp files. Since the
computer I just upgraded really doesn't use exim as a mailer, it isn't
affecting the installation; however, I will need to also update a server
which does run exim4. If this is a common issue, i would be most
thankful for any workarounds.
Best regards,
Calvin Wels
