I can't reproduce with the Zope 2.10 branch tip using cadaver, which
also uses libneon::

If your HEAD request is returning a 404, then you have a different
problem (the resource is not there). AFAICT, the presence of the
response body is contra-spec, but has not caused any other issues that I
know of in the eight years I've been using DAV against Zope.
