Dead link in watched topics list

I seem to have a dead link at the top of my watched topics list, it's been there for a couple of weeks now.

It has no author, was last replied to on Dec 31st and the url is http://forum.baby-gaga.com/about.html.

I cannot remove it from my watched topics list, as this error is generated every time I try:

ERROR SQLModel::dbQuery  ELETE FROM members_topics_watch WHERE id=11189 AND topic_id IN () LIMIT 1
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') LIMIT 1' at line 1
Warning: Cannot modify header information - headers already sent by (output started at /www/app/models/sql_model.php:137) in /www/app/controllers/app_controller.php on line 56

I don't know if anyone else is having the same issue, but whatever you can do about it is lovely, thank you kindly.
