Mark Sapiro added the comment: One additional observation. The original message contained no Content-Transfer-Encoding header even though the message body was raw koi8-r characters. Adding
Content-Transfer-Encoding: 8bit to the message headers avoids the issue, but that is not a practical solution as the message was Russian spam received by a Mailman list and the resultant KeyError caused problems in Mailman. We can work on defending against this in Mailman, but I suggest that the munge_cte code in generator._write() avoid the documented possible KeyError raised by replace_header() by using __delitem__() and __setitem__() instead as in the attached generator.patch. ---------- keywords: +patch Added file: http://bugs.python.org/file43394/generator.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27321> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
