What does ItemTree.items field have to do with Activity.description 
field? I thought we're talking about the Object(schema=IItemTree) field 
inside IActivity here?

As you correctly stated in your own reply, this doesn't comply with the 
List() field. The List() field expects a list object with a bunch of 
unicode values in it, e.g.: [u'text', u'more text', ...].

That's not a unicode declaration, that's just the source code encoding. 
It has nothing to do with whether your objects are unicode or not.
