[Mailman-Users] Digest Errors

[Larry Hansford]

My system (Red Hat 7.2, Mailman 2.1.2) has been running fine since it was 
installed, until this past Thursday.  It is now giving errors on the daily 
senddigests command:

Cron <mailman at ash> /usr/local/bin/python -S   /home/mailman/cron/senddigests

Error Message:

Traceback (most recent call last):
   File "/home/mailman/cron/senddigests", line 94, in ?
     main()
   File "/home/mailman/cron/senddigests", line 86, in main
     mlist.send_digest_now()
   File "/home/mailman/Mailman/Digester.py", line 60, in send_digest_now
     ToDigest.send_digests(self, mboxfp)
   File "/home/mailman/Mailman/Handlers/ToDigest.py", line 130, in send_digests
     send_i18n_digests(mlist, mboxfp)
   File "/home/mailman/Mailman/Handlers/ToDigest.py", line 303, in 
send_i18n_digests
     msg = scrubber(mlist, msg)
   File "/home/mailman/Mailman/Handlers/Scrubber.py", line 257, in process
     url = save_attachment(mlist, part, dir)
   File "/home/mailman/Mailman/Handlers/Scrubber.py", line 349, in 
save_attachment
     ext = guess_extension(ctype, fnext)
   File "/home/mailman/Mailman/Handlers/Scrubber.py", line 80, in 
guess_extension
     if ext in all:
TypeError: iterable argument required


I have not made any changes to the system, other than installing the 
updates with Red Hat's up2date program.

Suggestions on what is causing this?

Thanks!
