Hello Pascal,

portal_catalog is returning a list of brains ...
So you are querying a list instead of a brain.
Instead try with:

item_brain = portal_catalog(id=this_is)[0]
(returning first brain in list)

or do a fail_safe one:
result = portal_catalog(id=this_is)
if result:
    item_brain = result[0]

After 1.5 years of Python, I'm still discovering 
richness (and still unable to understand what the 
hell Jim Fulton is talking about).
