Nextgen Gallery Warning Messages

I’ve just updated wordpress to 3.5 and also updated Nextgen gallery to 1.9.8 but i am getting this error message on gallery pages.

Warning: Missing argument 2 for wpdb::prepare(), called in /home/secretga/public_html/wp-content/plugins/nextgen-gallery/lib/tags.php on line 318 and defined in /home/secretga/public_html/wp-includes/wp-db.php on line 990

Can someone help me and tell me how i can fix this.
