As this was fixed in 3.3 that means all actively maintained versions have the
fix, and so closing as fixed.

I think it works with the other test also now. Have also included the failed
test mentioned by Tres in the patch since it wasn't present in the python2.7

I don't have the expertise required to do the 2.7 backport. My naive attempt
is attached, but the message attribute is not preserved (test failure). If

A backport to 2.7 would be in the interest of the Zope community (I dare say
;)), at least in ours.
In our project, after having migrated to Zope 2.13/Python2.7 we found this bug
and now we are quite worried what else might happen with our huge pickled

I modified your script to run under both python2 and python3. I get the error
for 2.5, 2.6, and 2.7. The script produces the same output (without the
