Probably you have a name clash with an FSPythonScript.  Your code
tries to copy the items from 'parent', rather than from 'layout',
which could be the real source of the problem.  Try::

   layout = getattr(parent, 'default_template', None)
   if layout:
       obs = layout.objectIds()
       copy_data = layout.manage_copyObjects(obs)
       f.manage_pasteObjects(copy_data)
