Hi,
I ran into this bug on an Ubuntu system. It's triggered when the sqlite
data file for the specified user isn't writable by the user that dspam
is running as.
Using the reproduction technique suggested by Patrick, I get the following:
#cat <<EOF >/tmp/testmail
> From: s...@spammer.com
> To: cput...@wiresong.ca
> Subject: Test
>
> This is a test mail
> EOF
# chown root /var/spool/dspam/data/local/colin/colin.sdb
# ls -l /var/spool/dspam/data/local/colin
total 119748
-rw-rw---- 1 dspam dspam 1822334 May 29 09:11 colin.log
-rw-r----- 1 root dspam 120668160 May 29 09:11 colin.sdb
-rw-rw---- 1 dspam dspam 20 May 29 09:11 colin.stats
#sudo -u dspam /usr/bin/dspam --deliver=spam,innocent --user colin
--stdout < /tmp/testmail
*** crash similar to what Nicol reported ***
#chown dspam /var/spool/dspam/data/local/colin/colin.sdb

This is a test mail
I got into this situation while I was training dspam from the command
line. I ran the training script as root, so when
/var/spool/dspam/data/local/colin was created, it was owned by root.
Then when postfix tried to run dspam as the user "dspam," it couldn't
write to /var/spool/dspam/data/local/colin/colin.sdb and crashed. Fixing
the file ownership makes the problem go away.
