The problem seems to be an escaped apostrophe by esc_attr() in the profile title becomes '
which makes a preg_replace() later on fail by returning null which causes the reply to disappear. Also there is one sprintf() too much in the code for v6.4.9. I’m not 100% sure about the reason because I have limited debug possibilities in wordpress[.]com on a live weblog.

Changing the code in ‘includes/functions_quote.php’ like this works:

<                                                 $view_profile_text = sprintf( 
---
>                                                 $view_profile_text = esc_attr(sprintf( 
257,258c257,258
<                                                         esc_attr( sprintf(__( 'View %s\'s profile', 'bbpress'),
<                                                         $user_name))
---
>                                                         __( 'View %s\'s profile', 'bbpress'),
>                                                         $user_name)
272c272
<                                                 $content = preg_replace( '#'.$new_link.'#is', '<span class="bbp-author-name">'.$user_name.'</span>', $content );
---
>                                                 $content = preg_replace( '#'.preg_quote( $new_link, '#' ).'#is', '<span class="bbp-author-name">'.$user_name.'</span>', $content );

I let you decide if there are any security implications of that additional preg_quote(), but it makes it work with esc_attr(), alternately I guess the escaped apostrophe character can be removed from the view profile string.

OK, yes, it looks like some filter to escape characters. In my setup using wordpress[.]com it probably generates a PHP error because there is no content at all with “Quotes” enabled without that patch. I noticed an alternative is to edit the reply, select “CODE” view, and change the div tag “bsp-quote-title” to something else, and the reason that shows the reply is because it’s not recognized as “Quote” anymore.
