Most likely it is a CatalogAware object that is in the catalog, but no 
longer exists.

Clean up the catalog, or Just put an exception around it.


Whenever I need to call getObject I pass the catalog result through this 
small utillity function.

## Script (Python) "util_brains2objs"
##bind container=container
##bind context=context
##bind namespace=
##bind script=script
##bind subpath=traverse_subpath
##parameters=cat_results
##title=Turn catalog brains to objects
##

# Turns a list of catalog results (brains) into objects,
# skipping dead catalog results
results = []
for cat_res in cat_results:
     try:
         results.append(cat_res.getObject())
     except: # sometimes there are dead objects in the catalog
         pass
return results
