One more quick note about the "intermittently" aspect: It seems likely that the intermittence is due to varying data content in this RSS feed which my code reads via "feedparser" Python module (which is Mark Pilgrim's well-known open source RSS reading software Universal Feed Parser):
http://rss.news.yahoo.com/rss/health Sometimes perhaps some data in the above feed results in the "5 args vs. 1 arg" think happening in a behind the scenes unicode processing step of TG.
