 {{{wp_insert_term()}}} can return a {{{WP_Error}}}, but admin-ajax.php
 does not catch these errors.  In two places (when adding post and link
 categories during post/link creation), the result of
 {{{wp_insert_term()}}} is blindly assumed to be an array, which will cause
 a fatal error.

 Attached checks for errors and skips that category.  The patch does not
 implement any error messaging to the user.
