  What you really want is the reader to not break on namespace
errors or warning, only if a well-formedness error was found,
which was fixed in the last chunk of that patch:

http://git.gnome.org/browse/libxml2/commit/?id=6c91aa384f48ff6d406553a6dd47fd556c1ef2e6

Unfortunately I don't see any workaround beside applying that patch :-\
