sa-learn problem

[David Corbin <dc...@machturtle.com>]

I'm having a problem with sa-learn (version 3.1).  Here's a snipit of the 
debug output:
       
-------begin------
[787] dbg: locker: safe_lock:

ERROR: the Bayes learn function returned an error, please re-run with -D for

------end------

The .spamassassin directory is rwx for me, and all the files in it are rw for 
me.  I don't understand what's going on.  Can someone tell me how to get this 
working again?
