[Mediawiki-l] no categories in keywords metatags

[FxParlant]

Hi,

I've noticed that only the title of my pages appears in the keyword
metadat of my pages. Is there some place to enable the addkeywords
function with category links ?

I'm running :

# MediaWiki: 1.8.2
# PHP: 5.2.0 (cgi)
# MySQL: 4.0.27
# Extensions:

    * Special pages:
          o NewestPagesBlog
    * Parser hooks:
          o CharInsert,
          o DynamicPageList2 (version 0.7.7),
          o ParserFunctions by Tim Starling
          o Semantic MediaWiki (version 0.5),

I've noticed that the same thing happens on meta.wikimedia.org (running
1.9 alpha): the title is displayed in the metatags keywords list.

Maybe an extension breaks this feature.

Thanks for any advice.

François
