Can't call method "id" on an undefined value at /usr/share/perl5/HTML/Microdata.pm line 91

I am seeing access through undefined value on the Microdata on http://neurosciencenews.com/profanity-honesty-psychology-5944/. Here is a reproduction one liner:

$ perl -MLWP::Simple -MHTML::Microdata -e 'my $url=q{http://neurosciencenews.com/profanity-honesty-psychology-5944/}; my $htmldoc=get($url); HTML::Microdata->extract($htmldoc, base => $url);'

I think this is fixed by #9.
