It's a bit early for you to use this if you haven't patch your BuddyPress as Dan explains above.
This is now fixed in the trunk
Ticket here: http://buddypress.trac.wordpress.org/ticket/4770
Changeset: http://buddypress.trac.wordpress.org/changeset/6725
If you use a different theme than BP Default, i suggest you to search the /forums/forums-loop.php, then search for something like :
<a class="topic-title" href="<?php bp_the_topic_permalink(); ?>" title="<?php bp_the_topic_title(); ?> - <?php _e( 'Permalink', 'buddypress' ); ?>">
Then you'll need to delete in the title attribute of this link <?php bp_the_topic_title(); ?>
Hope it helps you to customized your style.
And thanks a lot for your interest in my plugins :)
