Weird SQL errors when Editing Posts

I went in to change a few categories for some old posts from a few years ago and after i change the selection for the categorie i get all these errors:

at the top:
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 'new album has a tentative title of Yoshimi vs. the Pink Robo]
UPDATE wp_posts SET post_content = 'not a news site, but this is damn exciting - wayne (17k image)Digimon lose first-round draft-pick Steven Drozd to Cardcaptors in furious trading

at the bottom:
Warning: Cannot modify header information - headers already sent by (output started at /home2/xxx/public_html/xxx/wp-includes/wp-db.php:98) in /home2/xxx/public_html/xxx/wp-admin/post.php on line 381

Warning: in_array(): Wrong datatype for second argument in /home2/xxx/public_html/xxx/wp-admin/post.php on line 404

Warning: Invalid argument supplied for foreach() in /home2/xxx/public_html/xxx/wp-admin/post.php on line 409

Warning: Missing argument 2 for email_notification_send() in /home2/xxx/public_html/xxx/wp-content/plugins/wp-email-notification/email_notification_2.1.php on line 55

I’ve turned off the email notification plugin but it only gets rid of that single Warning… The others are still there…

Any ideas of what’s going on?

Thanks
