interesting. this is happening because of an implicit assumption. when mf2py gives us an author property, we assume it's an object (a dict), but in these two cases, there's an outer author object with an inner author property that's just a list of strings.

is that valid? do i need to handle that? not sure yet. cc @kartikprabhu

here are two examples. mf2py parses this markup from http://www.pierre-o.fr/blog/2014/08/02/permashortlinks/ :

<span class="byline author vcard">
  Posted by <span class="p-author fn">Pierre Ozoux</span>
</span>

and returns this JSON (bridgy log):

{'items': [{
  'type': ['h-entry'],
  'properties': {
    'author': [{
      'type': ['h-card'],
      'properties': {
        'name': [u'Pierre Ozoux'],
        'author': [u'Pierre Ozoux'],
        },
      'value': u'Posted by Pierre Ozoux',
      }],
    'url': ['http://www.pierre-o.fr/s/9.htm'],
    ...

same thing with http://maniaravings.com/blog/2013/12/how-do-you-worship-to-please/ :

<p class="the_author h-card vcard author">
  By <a rel="author" class="fn p-author" href="%20">Jaffer</a>
</p>

mf2py returns this (bridgy log):

{'items': [{
  'type': ['h-entry'],
  'properties': {
    'author': [{
      'type': ['h-card'],
      'properties': {
        'name': [u'Jaffer'],
        'author': [u'Jaffer'],
      },
      'value': u'By Jaffer',
    }],
    'url': ['http://maniaravings.com/blog/2013/12/how-do-you-worship-to-please/'],
    ...

@kartikprabhu says to ignore the inner author property. easy to do. thanks kartik!
