[Richard Humphrey]

After upgrading to 3.0 pre1 from 2.63 I am getting the following error 
when running sa-learn. Running Redhat 9 server. How can i fix this? 
Note, I get the same error in my maillog when trying to autolearn spam/ham.

sa-learn --spam --mbox /var/spool/mail/catchall
# sa-learn --spam --mbox /var/spool/mail/catchall
