Only 1 rdf_value and content_item is returned with multiple available in feed

What steps will reproduce the problem?
1. The feed: 

http://www.politie.nl/rss/ab/gemeenten/drenthe/aa-en-hunze.xml

2. The lines of code:

import feedparser
d = 
feedparser.parse('http://www.politie.nl/rss/ab/gemeenten/drenthe/aa-en-hunze.xml
')
for entry in d['entries']: print entry

3.

What is the expected output? 

 'content_item': {'rdf:about': u'Alinea'},
 'content_item': {'rdf:about': u'Categorie'},

And also the value of both items

'rdf_value': u'Verkeer',
'rdf_value': u'<text of the content item: Alinea>',

Only 1:
'rdf_value': u'Verkeer',
 'content_item': {'rdf:about': u'Categorie'},

Start by running the reported feedparser.parse reproduction against the provided RSS URL and inspecting each entry. Trace how multiple rdf_value and content_item elements are represented; done means both available items and their values are retained in the parsed entry.
