Comment (by birgire):

 I noticed a typo in [attachment:"41801.2.diff"] in
 {{{wp_attachment_is()}}}, where it adds a {{{wp_get_audio_extensions()}}}
 instead of {{{wp_get_image_extensions()}}}.

 Additionally I wonder if {{{wp_get_image_extensions()}}} should be used in
 {{{translate_smiley()}}}:

 includes/formatting.php#L2802

 I'm not so sure about {{{WP_Theme::get_screenshot()}}} though:

 wp-theme.php#L962
