Comment 14 for bug 256086

I am re-opening this bug. I've been adding more RSS feeds with normal-looking titles, and several of them exhibit this behaviour: When I initially try to subscribe, Thunderbird displays "Verifying feed" but never gets past that. If I try to cancel and it asks me if I'm sure, the yes/no choice doesn't affect the outcome. A broken folder is created, often with a name with numbers in it, that you can't delete, and the folder is empty and does not receive new RSS items from the feed. For me, the following feeds have this behaviour (so far):

http://interfacelift.com/wallpaper_beta/rss/
http://rss.cbc.ca/lineup/topstories.xml

To contrast (if you can detect any difference) here are some feeds that do work:
http://www.projectcensored.org/feed/
http://www.democracynow.org/democracynow.rss
http://indymedia.org/en/main-features.rss
http://feeds.feedburner.com/Engrishdotcom

This behaviour is consistent and a little aggravating for an otherwise acceptable aggregator.
