[Spambayes] I seem to have stumbled upon a (persistent) spamcount > nspam bug

[Edgar Matzinger]

ls,

   after getting these messages:
-------------------------------8<---------------------

And after browsing (and googling) the internet, the above error seems
to point to a corrupt DB file. Even after recreating this DB file
from scratch *and* after updating to spambayes-1.1a1 and recreating
the same DB file, this problem keeps existing. The platform spambayes
is running on is (Intel pentium) Fedora Core 5. I've used the following
comnmand to recreate the DB file:
-------------------------------8<---------------------
$ # Empty hammie DB
$ echo -n > /usr/local/share/spambayes/hammie.db
$ # Retrain
$ sb_mboxtrain.py -f -d /usr/local/share/spambayes/hammie.db -g \
  $HOME/EMail/Inbox/inbox -g $HOME/EMail/Inbox/NeoNixie -g \
  $HOME/EMail/Inbox/SpareTimeGizmo -g $HOME/EMail/Inbox/Evolution -s \
  $HOME/EMail/spam/spam
-------------------------------8<---------------------
NB I've specified the -f option to force a retrain of already trained
    messages.

Can anyone of you shed some light on this issue?

MTIA, cu l8r, Edgar.
