on startup. Worked fine, then I rebooted the machine 
(shut down Spambayes through the Web interface) and 
then it simply refused to boot up with the above 
message. Error seems permanent, unless user does 
something drastic (ie. destroys the database). I'm 
running Win98 Se, using pop3proxy with Outlook 6 SP1, 
starting the program with

c:\ohjelmatiedostot\python22\python.exe 
c:\ohjelmatiedostot\spambayes\pop3proxy.
py -b

Hard drive is a 80GB model, partitioned into one single 
partition using FAT32, 45,7GB still free. Spambayes 
version is 1.0 A4.

The same problem also occurred with Alpha 3, it refuses 
to start up with the message

After a fresh install, the program usually works fine for a 
while. Every reboot does not appear to mix things up, it 
only seems to go bad after it has been running for a 
while and the user has classified enough messages. I run 
my comp mostly 24/7, so reboots are rare and 
Spambayes is usually running unless I need to boot.

Mark, the Outlook addin never uses dumbdbm, does it?  Looks 
like manager.py looks for bsddb3, and, if it fails to find one, 
uses a PickleStorageManager.  I don't want to give up the 
option of using a PickleStorageManager, since no bugs are 
ever reported against that (low tech == low risk <0.2 wink>).

Well, fixed in Python anyway.  If you still care, add a
feature request that Outlook fail to register unless we have
a bsddb database

The "dumbdbm._Database instance" in the traceback is a sure 
sign of a recently-diagnosed critical problem.  Since you're 
using Outlook, using the Outlook addin instead of pop3proxy 
will cure it.  If for some reason you want to use pop3proxy 
with Outlook (I woudn't -- the Outlook addin is a joy), you'll 
need to install "a real" database.  Python 2.3 will ship with a 
current version of Sleepycat's Berkeley bsddb database.  For 
Python 2.2.3, that can be obtained separately from the 
SourceForge PyBSDDB project:
