New issue 2221 by address@hidden: Duplicate node errors in snippets
http://code.google.com/p/lilypond/issues/detail?id=2221

Some lilypond snippets are included more than once in the doc, under  
different tags. For each snippet a node is created from the @lydoctitle  
macro. As soon as a snippet appears twice we get a duplicate node error  
from texi2html.
