Youtube field type

Hi there, experiencing the same error as in this (closed) thread: https://forum.grabaperch.com/forum/07-16-2016-youtube-addon-php-errors.

Warning: Division by zero in D:\Noizebox\Web\Repos\nb_main\site\perch\addons\fieldtypes\youtube\youtube.class.php on line 123

Even more irritating the preview renders correctly.

I have defined the youtube api key in config.php:

define('PERCH_YOUTUBE_API_KEY', 'XXX');

The template is:

<perch:content id="video" type="youtube" label="YouTube URL" />
<perch:content id="video" type="youtube" width="800" label="YouTube URL" output="embed" />
