Wow, thanks for the quick fix! Looking forward to the new version.
In addition: would you be willing or would it be possible/feasible to implement some additional parsing? One small "error" that crops up often with Amazon descriptions (and that I'm correcting manually) is spaces before end tags (like "<p>BlaBlaBla </p>). It would be nice if Calibre could get rid of these, but I can live with manual editing of course.
