Post Format Image breaks with themes other than Twenty Thirteen

[crondeau]

I've tested the new post format features with 2011, 2012 and 2013 and a few others at random.

When using themes other than Twenty Thirteen the HTML outputted is as follows:

<div class="post-format-content">
<p><img src="<a href="http://test.bluelimemedia.com/wp/wp-content/uploads/2013/04/iStock_000009713448XSmall.jpg"><img src="http://test.bluelimemedia.com/wp/wp-content/uploads/2013/04/iStock_000009713448XSmall.jpg" width="300" height="198" alt="iStock_000009713448XSmall" class="wp-image-14 alignleft size-medium" /></a>&#8221; alt=&#8221;" /></div>

This happens, when you create the new post format, use the select/upload image button and select an image.
If you don't use the select/upload image button, and simply insert the image url, then the format is fine.

Confirmed with Twenty Twelve.

Introduced in [24021]. A similar bug with get_the_post_format_image() is mentioned in ticket:23964:16.

​http://core.trac.wordpress.org/attachment/ticket/23965/23965.7.diff fixes some other things related to slurping images and is merged with Sergey's patch (they need each other) - at this point, this ticket is a dupe, but I'll let the Trac gods decide what to do

Let's keep this ticket as a separate issue for easier tracking, as it's not directly related to caption.
