SOLVED: [Zope] AttributeError: _v_blocks

[Mike Murphy]

Yup, this was the problem! (duh)  The dtml-related sub-directories in
lib/python/Products corresponding to each item of the list of objects below
needed their permissions reset correctly.  Executing a 'find . -type d -perm
644' located all of directories needing fixing.  (I remember that I must
have did a 'chmod -R 644' before, that created the problem to begin with.)

Thanks for the help!

Mike
