Trouble with Bayes

[Martin]

Hi,

I'm running Mailscanner + spamassassin on Debian. I've noticed the 
following error when running lint:

20549] dbg: bayes: no dbs present, cannot tie DB R/O: 
/var/spool/MailScanner/spamassassin/bayes_toks

The bayes_toks IS there:

:/var/spool/MailScanner/spamassassin# ls -al
total 776456
drwxrwx--- 2 postfix postfix   12288 2006-08-30 13:03 .

-rwxrwx--- 1 postfix postfix 2658304 2006-07-25 18:17 bayes_toks.expire1004
* snip *

And the following setting in /etc/MailScanner/spam.assassin.prefs.conf:

bayes_path /var/spool/MailScanner/spamassassin/bayes

Any clue what's wrong here?

Thank you.
