Parsing never ends + lot of PHP Notice

[blat]

I'm trying to parse content of this article: http://www.jornalcorreiodonorte.com.br/2.1149/com-a-chegada-do-ver%C3%A3o-aten%C3%A7%C3%A3o-deve-ser-redobrada-com-os-c%C3%A3es-1.2191389
I'm using v2.1.0.

This produces a lot of PHP Notice:

PHP Notice:  Trying to get property 'nodeName' of non-object in vendor/andreskrey/readability.php/src/Readability.php on line 1079
PHP Notice:  Trying to get property 'contentScore' of non-object in vendor/andreskrey/readability.php/src/Readability.php on line 1080
PHP Notice:  Trying to get property 'contentScore' of non-object in vendor/andreskrey/readability.php/src/Readability.php on line 1091
PHP Notice:  Trying to get property 'parentNode' of non-object in vendor/andreskrey/readability.php/src/Readability.php on line 1092

Those 4 lines are repeated million times (I guess we are in an infinite loop).

My code is very simple:

$readability = new andreskrey\Readability\Readability(new andreskrey\Readability\Configuration());
$readability->parse(file_get_contents('http://www.jornalcorreiodonorte.com.br/2.1149/com-a-chegada-do-ver%C3%A3o-aten%C3%A7%C3%A3o-deve-ser-redobrada-com-os-c%C3%A3es-1.2191389'));

Indeed enters into an infinite loop. Will investigate later.

in Readability.php, function rateNodes, the while loop doesn't check if parentNode is null.

Few ways to fix it, the easiest one:
while ($parentOfTopCandidate && $parentOfTopCandidate->nodeName !== 'body') {

I attached an example file that triggers the loop (I cleaned the html as much as I could to keep the error)
