Comment (by mattyrob):

 I'm not 100% sure how phpmailer works but some of this code may be
 contradictory.

 We are checking for Content-Type and setting it as text/plain if it is not
 set.

 However, I have a plugin that passes some  mail via wp_mail() that sets
 the Content-Type as text/html. With his diff the Content-Type will be left
 alone but the code still invokes $phpmailer->IsHTML( false ); which
 presumably tells phpmailer that the email isn't html when in fact it is!

 Something like this might avoid this problem (if indeed it is still a
 problem after the patch.

 {{{
 if ( !isset( $content_type ) ) {
         $content_type = 'text/plain';
         $phpmailer->IsHTML( false );
 } elseif ( isset( $content_type) && ($content_type == 'text/plain' ) {
         $phpmailer->IsHTML( false );
 } elseif ( isset( $content_type) && ($content_type == 'text/html' ) {
         $phpmailer->IsHTML( true );
 }
 }}}
