[Zope-PTK] Rename error on Desktop

[matsuda-toshio@fujielectric.co.jp]

Hello, PTK users and developers.

I'm using Zope-2.1.6 + ZopePTK-0.7.1. Everything is ok, but I am now
puzzled by the following problem:

On the Desktop (opened by 'My Stuff' link), when I click 'Rename'
button, input a new ID and click 'Ok', then a Zope Error is raised.

The message below is one when trying to rename the object of
'Document' type.

Have you experienced the same problem? Any comments are appreciated.
Thank you.
