Almost all extensions in SVN now use wfLoadExtensionMessages to load messages. In some i18n files a hack has been implemented to allow some sort of fallback using something like "$messages['kk'] = $messages['kk-cyrl'];" This needs to be added for all extensions. Those extensions not using wfLoadExtensionMessages do not support fallback languages or have their own implementation. It would be a Good Thing if fallback was supported using the $fallback defined in MessagesXx.php files at least for extensions using wfLoadExtensionMessages.
Fixed in r30440 by Nikerabbit.
