Error When Replying to a Comment on a Pic

[Xx_True_Dachshund_xX]

I tried to reply to a comment on one of my pictures and I get this message:

[code:1]
Warning: pg_query() [function.pg-query]: Query failed: ERROR: CONTEXT: SQL statement "SELECT generate_picture_comment_ltrees( $1 )" PL/pgSQL function "update_picture_comment_ltrees" line 2 at PERFORM in /usr/home/sites/www.fanart-central.net/www/comments.php on line 377

Database Error: ERROR: CONTEXT: SQL statement "SELECT generate_picture_comment_ltrees( $1 )" PL/pgSQL function "update_picture_comment_ltrees" line 2 at PERFORM

SQL: INSERT INTO picture_comments (user_id, ipaddr, reply_to, comment, comment_date, pid) VALUES ('103392', '65.184.88.73', '3670266', 'Thanks! Yeah my style has changed so much since then lol!', now(), '793140'[/code:1]

The picture I tried to reply on was this:

Ouch, that is not cool. I think I can guess the problem, but ... damn.

The short explanation is that this error can be triggered if you're replying to a comment, and one of the comments in the reply chain was removed before processing.
