SQL error when a new user signs up.

When a user creates and account on my site, this appears in the log:
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 '377, 0, 0)' at line 1 query: INSERT INTO subscriptions_user (uid, digest, last_sent) (377, 0, 0) in /home/chelmsf/public_html/includes/database.mysql.inc on line 172.

It looks like it needs to be VALUES (377, 0, 0)

(I have MySQL version 5.0.27)
