[Mailman-Users] Cron errors

[Daniel D Jones]

Getting the following complaints from the senddigest cron job:

Traceback (most recent call last):
  File "/var/lib/mailman/cron/senddigests", line 94, in ?
    main()
  File "/var/lib/mailman/cron/senddigests", line 86, in main

  File "/var/lib/mailman/Mailman/Digester.py", line 60, in send_digest_now

    msg = scrubber(mlist, msg)

    msg.set_payload(text, charset)
  File "email/Message.py", line 218, in set_payload
  File "email/Message.py", line 242, in set_charset
TypeError: us-ascii

Not a  python programmer, so I have no idea what to do to deal with this.   
Suggestions?
