[Mimedefang] Errors with Mimedefang 2.21 / SA 2.42

[Nate Carlson]

I'm getting the following errors on quite a few messages after an upgrade
from SA 2.2x -> 2.42:

Oct 14 10:18:40 conformity mimedefang-multiplexor: Slave 1 stderr: Use of uninitialized value in concatenation (.) at /usr/lib/perl5/site_perl/5.6.0/Mail/SpamAssassin/EvalTests.pm line 1048.

The message is still properly handled (if spam, bounce it off to a
different user, if not, deliver it), but it'd be nice to get rid of the
errors.. anyone have any ideas?
