Let me look at the structure of the HTML file...  Something does look
a little off.  I see that one of the links in the table of contents
(not the sidebar, but the text right after the abstract), look like
this:

    <a href="/#(part._example)" class="toptoclink" pltdoc="x">1<span
class="hspace">&nbsp;</span>Example: Playing sound from a raw
buffer</a>

where the leading slash is causing the anchor link to break.
