When you switched python versions, did you use a cleanzope tree?

if not (or just to clean it out) try deleting all the .pyc files in your
zope tree. I've seen this error when distributing .pyc files from 2.0
machines to 1.52 machines.

cd $ZOPEHOME
find * |grep .pyc$ |xargs rm

i use thiswhenever I seem to be having an issue, just to clear out
potential problems there (have had that before).
