XMLRPC returns category name instead of category description

I am using the XML-RPC interface into wordpress, and when I use the wp.getCategories XML-RPC call, I get the category name twice in the returned data – instead of the category description, the category name is repeated.

The problem comes from the routine mw_getCategories inside xmlrpc.php – it reads:

function mw_getCategories($args) {
...
  $struct['description'] = $cat->name;
  $struct['categoryName'] = $cat->name;
...
  return $categories_struct;
}

whereas I’d expect it to be

function mw_getCategories($args) {
...
  $struct['description'] = $cat->description; //<<<<<
  $struct['categoryName'] = $cat->name;
...
  return $categories_struct;
}

I checked the 2.7RC1 – the same problem exists there.

Is this a feature or a bug? Not sure how I should go about this – I am an old developer, but new to WordPress, so I don’t know the proper ‘etiquette’ yet…
