I believe this all combined is the source of the problem.

Later versions of Perl 5.8 (I believe in 5.8.1) changed the
automatic flagging of file handles to UTF-8 according to a
locale setting. So when a log line is composed of parts
derived from a template (presumed UTF8 in your case but
not in reality) combined with data strings, the result is
somehow wrong (has UTF8 flag on, but contains single-byte
8-bit characters).

The fix is to always set locale to C (LANG=C) in the process
starting amavisd (this is recommended anyway, regardless of
version of Perl), or to upgrade Perl to 5.8.8. Best is to
to both, but I think one or the other would suffice.
