I have been using Zope 2.10.4-final, python 2.4.4, win32 for quite awhile... I recently started a new project using Zope 2.11.4-final, python 2.4.4, win32 and proceeded with my normal programming but I am receiving an error that I haven't received before.

Traceback (innermost last):
Module ZPublisher.Publish, line 119, in publish
Module ZPublisher.mapply, line 88, in mapply
Module ZPublisher.Publish, line 42, in call_object

Module zope.contenttype, line 39, in text_type
IndexError: string index out of range

I did a little deductive reasoning and took parts out until it didn't error out anymore and it seemed when I took the following lines out it didn't error:

If I have both, one, or the other in it will throw the error. If I take both of these out then it will not.
