Bayes sometimes not used

[Juliano Simões]

Hi Guys,
I have noticed a strange behavior of SA, after upgrading from
version 2.64 to 3.0.1. Sometimes, the same message is scored
with bayes, sometimes not.
See below sample outputs from subsequent executions of
"/usr/bin/spamassassin -tLD < spam_msg_file":

This seems to happen regardless of message content or SA score.
ENVIRONMENT:
- running spamd with options: "-L -x -u spamd -H /home/spamd
 --socketpath=/tmp/spamd.sock --max-children=7 --daemonize"
- only use sitewide setup
- ran "sa-learn --sync" right after upgrade from 2.64 to 3.0.1
- local.cf includes:
   required_score 6.6
   report_safe 0
   use_dcc 0
   use_pyzor 0
   use_razor2 0
   skip_rbl_checks 1
   rbl_timeout 1

   use_bayes_rules 1
   bayes_auto_learn_threshold_nonspam -2

Version 2.64 was very consistent when it comes to using bayes.
Any clues on what may be causing this problem on 3.0.1?
