WordPress 2.2 DBError

Hi,

Thanks for the great CMS.
I occassionaly get this error when writing/submitting a post. It started happening since I upgraded to WordPress 2.2

Error:

WordPress database error: [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 ”\’) as score FROM wp_posts where id=3544′

at line 1]
SELECT MATCH(post_content, post_title) against (‘\’) as score FROM wp_posts where id=3544;

Any ideas what might be causing the problem?

Thanks in advance
