I failed to reproduce this in my Zope CVS.

It is puzzling indeed!

Does "SESSION['info']" has a key "num" or do you expect
to access the "num" passed as parameter?
In this case, it might have something to do with permissions,
as Zope sometimes turns insufficient permissions into KeyError.
However, I expect your "SESSION['info']" is a standard dictionary
and then access should by unprotected.
