I was checking out the state of spam filtering on my servers today and 
noticed in the logs a lot of the following errors:

Traceback (most recent call last):
   File "/usr/bin/sb_filter.py", line 257, in ?
     main()
   File "/usr/bin/sb_filter.py", line 248, in main

     return self.h.filter(msg)

     assert spamcount <= nspam
AssertionError
procmail: Program failure (1) of "/usr/bin/sb_filter.py"
procmail: Rescue of unfiltered data succeeded


I even tried to upgrade to the latest 1.0.4 version and it's still 
happening.  I checked the archives and see reports of this problem going 
back a couple years!

If it matters it only seems to get triggered by very spammy messages.
I'm running sb_filter.py out of Procmail.  OS is RHEL4.
