Hi folks, I hit the same sort of problem as a couple of other people apparently have, eg:
http://mail.python.org/pipermail/mailman-users/2006-November/054246.html I hit this when Mailman attempts to send digests. I thought I'd tracked the issue to the way Charset is used within Mailman/Scrubber.py, on line 193 (some modifications by me to print debug output): charset = None lcset = Utils.GetCharSet(mlist.preferred_language) print "getting charset for preferred language:", repr(lcset) lcset_out = Charset(lcset).output_charset or lcset print "lcset_out is:", repr(lcset_out) Which yields: getting charset for preferred language: 'us-ascii' lcset_out is: u'us-ascii' It appears that Charset returns a unicode string for its .output_charset, which python2.4 email.Message.set_charset() does not recognise as a string, and it isn't a Charset either, so a TypeError is raised. I don't know enough about why .output_charset is being used, or why it is unicode, but it seems that changing line 193 to read: lcset_out = Charset(lcset) or lcset would prevent this error. However, something else is also returning a unicode string, since after changing Scrubber, you end up with this error: Traceback (most recent call last): File "/usr/lib/mailman/cron/senddigests", line 94, in ? main() File "/usr/lib/mailman/cron/senddigests", line 86, in main mlist.send_digest_now() File "/var/lib/mailman/Mailman/Digester.py", line 60, in send_digest_now ToDigest.send_digests(self, mboxfp) File "/var/lib/mailman/Mailman/Handlers/ToDigest.py", line 142, in send_digests send_i18n_digests(mlist, mboxfp) File "/var/lib/mailman/Mailman/Handlers/ToDigest.py", line 339, in send_i18n_digests mcset = msg.get_content_charset('') File "/usr/lib/python2.4/email/Message.py", line 805, in get_content_charset charset = unicode(charset, 'us-ascii').encode('us-ascii') TypeError: decoding Unicode is not supported I haven't worked out what this other thing is as yet. Alternately, patching email/Message.py (line 803) to ignore a charset that is a unicode string seems to work, but is probably fragile or broken in other ways: # charset character must be in us-ascii range try: if not isinstance(charset, unicode): charset = unicode(charset, 'us-ascii').encode('us-ascii') except UnicodeError: return failobj I hope this helps someone more knowledgable about Mailman to work out what the underlying problem is. -- Justin Warren <[EMAIL PROTECTED]> seafelt.com: Making sense of a sea of data. ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
