Simple Recipe Breaks in Latest Version

[Tegan]

I've been trying to help someone with a simple Blog recipe. It didn't work for her, but I was having no problem running it. I finally figured out that I was running 0.7.43 while she was running the latest version, 0.7.45. So I upgraded, and now the recipe doesn't work. Any idea why not?

class AdvancedUserRecipe1297484821(BasicNewsRecipe):
  title = u'Book Blogs'
  oldest_article = 30
  max_articles_per_feed = 100
  use_embedded_content = True

  feeds = [(u'Book Goggle', u'http://mybookgoggles.blogspot.com/feeds/posts/default'), (u'Book Chick City', u'http://www.bookchickcity.com/feeds/posts/default')]

What error do you get?

Sorry, I should have given details.

In the older version, the recipe works great, produces the expected articles, yay, etc.

In the newer version, the recipe runs and generates a book that has this for the contents:
Failed feed: Book Goggles
TypeError('expected string or buffer',)
Table of Contents
Failed feed: Book Chick City
Failed feed: Book Goggles

After I upgraded and discovered that I got the same error, I rolled back my version to 0.7.43 and ran the recipe again. And again it worked fine. So my theory is that something changed between the versions.

I haven't yet tried 0.7.44, as I had to get some sleep.

Yeah, I uploaded a fixed build, just re-install 0.7.45 and you should be fine.

Dear Kovid,
is reinstalling applies to the linux (Archlinux) version as well?
I'm on 0.7.45 already, and getting the same error:

If you are installing the official calibre binary yes. If you are installing the distro package, no.
