__init__() got an unexpected keyword argument 'errors'

Hello!
Out of the blue, Mailman stopped working and produced
this bug message on some pages and as a reply to mails
sent to a list:

Traceback (most recent call last):
  File "/usr/local/mailman/scripts/driver", line 87, in

  File "/usr/local/mailman/Mailman/Message.py", line 206,
in __init__
    errors='replace')
TypeError: __init__() got an unexpected keyword
argument 'errors'

Python information:

Variable Value
sys.version 2.2.2 (#1, Apr 18 2003, 08:23:15) [GCC 3.3
20030226 (prerelease) (SuSE Linux)]
sys.executable /usr/bin/python
sys.prefix /usr
sys.exec_prefix /usr
sys.path /usr
sys.platform linux2

The Mailman log "error" shows the same output, nothing
in any of the syslogs.

Can somebody help?

Sorry to have bothered you ... reinstalling 2.1.1 from the SuSE
8.2 CD fixed it.
