I've also tried with 0.7.45 and have made no progress, for example using the full text RSS2 feed as set up below, I only get pages and pages of links, not the full text.
Code:
class AdvancedUserRecipe1297608992(BasicNewsRecipe):
title = u'The RISKS Digest'
oldest_article = 21
max_articles_per_feed = 100
feeds = [(u'The RISKS Digest', u'http://catless.ncl.ac.uk/risksrss2.xml')]
