This bug surfaces as multiple entries all with the same title, or with the title of an image.  See Scoble's RSS feed
(http://feedproxy.google.com/fastcompany/scobleizer?format\x3dxml) and (http://feeds.feedburner.com/lightspeedblog)for
examples.  Caused by incorrect xml? or incorrect rfeedparser processing? of the Yahoo media namespace tags.  Either
way it appears the Venus version of the (python) feedparser has a fix which is discussed in the links below.
