[Spambayes] BUG: filter dies after a processing a few emails

[Angus Berry]

Hi,

I think this is a bug:

I'm running Spambayes-1.0a6 on RedHat 9 (with python 2.2.2) using the POP3
proxy. I have upgraded from v1.0a4. The filter works fine for about the
first 15-20 of 100 emails, but seems to die at that point and then let
everything through.

I see the following message at the command prompt where I started Spambayes.

----
Traceback (most recent call last):
  File "/usr/bin/sb_server.py", line 440, in onRetr
    msg.setId(state.getNewMessageName())
  File "/usr/lib/python2.2/site-packages/spambayes/message.py", line 193, in

    (msg.c, msg.t) = self.db[msg.getId()]

    f = StringIO(self.dict[key])

Spambayes-1.0a4 seemed to work OK, but needed restarting every now and then.

thanks...
