Forgive my triple Post Hiccup. When Textmate posted my blog posts, I got errors.
Thinking the post had not completed, I retried until I figured out the problem.
If you use Wordpress V2.3 and post with Textmate, then don’t try to add a new category when posting an article. You get this problem:

  Fatal error: Cannot use object of type WP_Error as array in wp-includes/taxonomy.php on line 1010

Looks like I am not the only one.
