Component:  XML-RPC       |     Version:  2.9

--------------------------+-------------------------------------------------
 There appears to be a bug in the metaWeblog.newPost functionality of the
 XML-RPC which causes categories not to be assigned correctly to the new
 post if one or more of the supplied categories does not exist on the
 target blog.

 For example; the blog has the category 'Cat 1', and the post is submitted
 with two categories 'Cat 1' and 'Cat 2'.  This causes the post to be
 assigned to no categories at all.

 This is not the expected behaviour according to the metaWeblog API RFC
 (http://www.xmlrpc.com/metaWeblogApi): "On the server side, it's not an
 error if the category doesn't exist, only record categories for ones that
 do exist."

 A fix would be to check the return value of get_cat_ID() (around line 2216
 of xmlrpc.php) and only include it in the $post_categories array if the
 return value is > 0.

 This bug was found in 2.8.6 and exists in the currently available version
 of 2.9.
