Comment (by kovshenin):

 This is interesting, and not limited to post formats, but the `[embed]`
 shortcode with audio and video files. The problem lies within the
 `WP_Embed->shortcode` method, which calls the `wp_audio_embed` and
 `wp_video_embed` functions, both of which return the URL, and not the
 embedded media, because `WP_Embed->shortcode` runs when all other
 shortcodes are not registered yet.

 The reason it "works" is that the resulting URL is picked up by
 `WP_Embed->autoembed` and parsed again using `wp_audio_embed` or
 `wp_video_embed`, so if there's anything else on the same line that
 doesn't match the audio/video regexes, it fails. Even worse is when the
 resulting URL contains a `</div>` like in the content produced by the
 audio/video formats compat code. This breaks the theme's markup because
 both embed handlers don't escape the URL.

 [attachment:24070.2.diff] makes both embed handlers return the (undone)
 shortcode, regardless of whether the shortcode has been registered or not.
