 markoheijnen, it's "related" but it's not the same issue. jstraitiff
 reported the issue with regards to '''terms''' and your related link is to
 do with '''categories'''.

 I know that the official terminology refers to them both as being
 "taxonomies", but a bug definitely exists! Sure, the related link points
 to the fact that there should always be at least 1 selected category, but
 I'm not aware of a similar rule existing for terms.

 I tried jstraitiff's fix on our test server, but it doesn't resolve the
 problem completely. Here's an example:
 1) The current state of our post is assigned to the "Uncategorized"
 category, and the term "News"
 2) I want to remove the Term "News", so I remove it and send the XML. Our
 app sends terms as "terms_names" and the categories as "terms" (see XML
 snippet below). However, "News" still stays attached to the post.


 {{{

                 <member><name>post_tag</name><value>
                         <array><data></data></array>

         </struct></value></member>
         <member><name>terms</name><value><struct>
         <member><name>category</name><value>
                 <array><data>
                         <value><int>1</int></value>
                 </data></array>
         </value></member>
         </struct></value></member>
 }}}
