[Zope] security assertion needed for dictionary?

[Doyon, Jean-Francois]

Forgetting plone (which I know nothing about), dictionaries definitely
do NOT need security assertions (like lists, strings, integers and all
basic types).

Are you SURE it's a dictionary?  Most likely it just LOOKS like one when
represented as a string.

Try:

<div tal:content="python:repr(myFeed)">

To see exactly what it is ... It might be an instance of some object
that has a __str__ that makes it look like a dictionary?

I have the exact same problem and have been unable to find a solution
anywhere. Were you ever able to resolve this?
