when unable to insert comment into db

version 2.7.1 – 2.9.2

hi all,

when MySQL is not properly configured and fails to insert a comment (e.g. in case of unsupported character in message), WordPress behaves inproperly; this error is not checked within the file /wp-comments-post.php and the user is redirected to an invalid page (…/wp-comments-post.php#comment-) without any message.

There should be a check, in /wp-comments-post.php:83

$comment_id = wp_new_comment( $commentdata );
/*check*/if (!$comment_id) wp_die( __(‘Error: unable to insert the comment, because …’) );
