[Zope] Problems with IE Document on upgrading to zope 2.6.1

[Sreekanth S Rameshaiah]

Dear all,
Greetings!
We have been using IEDocument with version 2.5.1 seamlessly for 2 years
now. Today I upgraded zope from 2.5.1 to 2.6.1. After this the
IEDocument produce is broken. I get the following error.
How do I fix this?
