Details

I am running spamassassin-3.0.1-1, perl-5.8.6-1, db-4.3.21-1.

When trying to train the Bayesian classifier via:

sa-learn --spam --mbox --showdots Mail/spam

[where Mail/spam is of course in the mbox format]
I get:

Use of uninitialized value in numeric gt (>) at /usr/lib/perl5/5.8.6/i686-linux-thread-multi/DB_File.pm line 270.
Cannot open bayes databases /home/richard/.spamassassin/bayes_* R/O: tie failed:

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

Re-running w/ -D didn't seem to give me any helpful output.

I edited /usr/lib/perl5/5.8.6/i686-linux-thread-multi/DB_File.pm and set $db_version to 2 manually; after that, i got the following output when running sa-learn w/ the parameters mentioned above:

Cannot open bayes databases /home/richard/.spamassassin/bayes_* R/O: tie failed:

I am not sure whether this is a SA, Perl or DB problem.
This task depends upon

I just downgraded to db-4.2.52-1, and everything works just fine.

So this is definitely not an SA, but a DB or DB/Perl problem.

DB file format has changed between db 4.2 and 4.3. You need to upgrade your bayes database when switching to db 4.3
