Warning: in_array

Every thing was working fine. Naow I get the following message when I am trying to add an image to my blog. The pictures are still there. Everything works. I just get a page full of this message.
Warning: in_array() expects parameter 2 to be array, null given in /home/momcat/public_html/sierras_blog/wp-includes/query.php on line 2399
I think this started after the upgrade to the latest wordpress version, and I use the automatic install.
Thanks
