 Hello,

 I found a bug with some "self-closing tags" (like <img ... />) when they
 are in a field which is processed by the function sanitize_post_field.
 The bug occurs when there are no spaces between the last attribute of a
 self-closing tag and the "/>", for example:
 {{{
 <img src="picture.jpg"/>
 }}}
 instead of
 {{{
 <img src="picture.jpg" />
 }}}

 When the first is processed by sanitize_post_field (the one with no space
 between src="picture.jpg" and />), it is transformed to:
 {{{
 <img>
 }}}
 (Yes "<img>" and nothing else).

 I discovered this bug by using sanitize_post_field like this:
 {{{
 sanitize_post_field('post_content', force_balance_tags($my_content),
 $post_ID, 'db');
 }}}

 (At the beginning I just had <img src="picture.jpg">, it was transformed
 to <img src="picture.jpg"/> by force_balance_tags and retransformed to
 <img> by sanitize_post_field)

 Thank you for your attention,

 Frédéric.
