Spamassassin backport/log flood

[Brett Carrington <brettcar@segvio.org>]

I have spamassassin 2.63-0.backports.org.1 installed and it does it's
job fine, but the follow floods the log:

root@aion# tail /var/log/syslog
Feb 16 17:28:33 aion spamd[4885]: Failed to run FROM_AND_TO_SAME
SpamAssassin test, skipping: ^I(Can't locate object method

----
There are actually plenty of other similar failure for just about every
test type and I assume per message processed. The package actually still
manages to mark mail as spam or not and does it's job perfectly: it's
just filling up my logs to the point of uselessness. (I also figure that
getting these tests to -work- would be good.

Any ideas?
