Anyway, you spotted a missed optimization: it's now "fixed" in Python 3.3 and 3.4 by the following commits. Well, whatever is the problem, it is not fixed in python 3.3.0 (as you can see in https://travis-ci.org/mcepl/html2text/builds/4969045) as I can see on my computer. Actually, good news is that it seems to be fixed in the master branch of cpython (or the tip, as they say in the Mercurial world).
It's not a "fix", it's an optimization. Please understand that using the "is" operator on strings is entirely wrong.
