[Zope] Confera reply error

[davhsu@falcon.cchem.berkeley.edu]

I can't post a reply to a Confera message. I'm running Python 1.5.2,
Confera 1.2.0, and Zope 2.0.1. Similar errors have been posted in Zope
archive mailing lists and bug reports, but no solution or patch. Does
anyone know of a fix? Thanks.
