I have the following YAML in my blog post file (added trailing space to keep this site from rendering the embed):

media:<br>
  - <br>
    type: embed<br>
    embed_code: '< iframe src="//embeds.vice.com/?playerId=YjMwNmI4YjU2MGM5ZWRjMzRmMjljMjc5&aid=vice.com/the-vice-report&vid=F1YnVvcTqIhq0ZMtmGN6E8cTsIqt65QF&embedCode=F1YnVvcTqIhq0ZMtmGN6E8cTsIqt65QF&cust_params=embdom%3Dhttp%3A%2F%2Fwww.vice.com%2Fvideo%2Fyou-dont-know-shit-full-185%26topic%3Dnews%26aid%3Dyou-dont-know-shit-full-185%26auth%3DVICE+Staff%26keywords%3Dpoop%2Cshit%2Cnyc+waste%2Cbiosolids%2Chuman+waste%2Cwaste+treatment%2Csewage%2Cwaste+treatment+plant%2Cthe+vice+report%2Cvice+reports%2Cturds+to+treasure%2Ctoilets%26ac%3Dyes%26country%3Den_us%26contentId%3DF1YnVvcTqIhq0ZMtmGN6E8cTsIqt65QF&ad_rule=1&description_url=http%3A%2F%2Fwww.vice.com%2Fvideo%2Fyou-dont-know-shit-full-185&autoplay=1&share_url=http://www.vice.com/video/you-dont-know-shit-full-185" width="500px" height="282" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

The corresponding code in my partial is:

{{ media }}<br>
{{ if type == "embed" }}<br>
{{ embed_code }}<br>
{{ endif }}

What I get in my web site source is (another space added):

< iframe [email protected]__ [email protected]__ [email protected]__ [email protected]__ webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

Where do all the "[email protected]" things come from? What can I do to get the embed working?
