What is the expected output? What do you see instead?
Expected: rendering with a roman font. Instead, the body text of the article is 
rendered with a sans serif font.

Firebug blames the css rules in 
http://static.guim.co.uk/static/90997/common/styles/wide/article-top.css which 
are still being used, for some reason.

What operating system are you using, and what browser and version are you
using?

Mac OS X 10.4.11, Firefox 3.6.3

Clicking the readability bookmarklet a second time fixes the font, oddly enough.
