--lint reports "failed to parse line, skipping: _ _2_ _R_TEXT_"; can't find the problem

[snowcrash+spamassassin]

i have installed,

        > spamassassin --version
                SpamAssassin version 3.1.8-r454679
                  running on Perl version 5.8.8

after a recent sa-update, --lint returns,

        [7718] dbg: plugin: fixed relative path:
/etc/mail/spamassassin/updates/3.001008/updates_spamassassin_org/80_additional.cf
        [7718] dbg: config: using

        [7718] warn: config: failed to parse line, skipping: _ _2_ _R_TEXT_

but,

        > cd /etc/mail/spamassassin/updates/3.001008/updates_spamassassin_org
        > ls 80_additional.cf
                80_additional.cf
        > grep -i R_TEXT 80_additional.cf
        >

and, even,

        > cd /etc/mail/spamassassin
        > grep -rlni R_TEXT .
        >

suggestions as to what/where the issue may be?

thanks.
