0.4.3b2 on Zope 2.2.0

In my DataSkins.py, line 208 is the one marked below:

Well, that's the version I've got, and that is how the
__set_attr__ method reads. What do I check next?

Backtracking a bit more, line 46 in ArchiveImage.py is in
the manage_addArchiveImage method, marked below:

def manage_addArchiveImage(self, id, file, title='',
displays=None, precondition='',
                           content_type='', REQUEST=None):
      """
      Add a new ArchiveImage object.
      """
   # This constructor basically ripped off from Image/File
       id, title = cookId(id, title, file)
       self=self.this()
   # First, we create the ArchiveImage without data:
46>    self._setObject(id,
ArchiveImage(id,title,'',displays,content_type,precondition))
   # Now we "upload" the data.  By doing this in two steps,
we
   # can use a database trick to make the upload more
efficient.
       self._getOb(id).manage_upload(file)
       if REQUEST:
           try:    url=self.DestinationURL()
           except: url=REQUEST['URL1']
           REQUEST.RESPONSE.redirect('%s/manage_main' % url)
       return id

Does this help?

Thanks,
