Taxonomy translation

Hi all,

I have a multilingue site with english as default language and french as other language.
All my taxonomy is correctly translated all over my site.
Specially in nodes, views, and other modules like "site_map".
The only place there are not translated is in "tags" page : http://www.mydrupal.com/fr/tagadelic

Did I miss something ?
Or is it a bug ? If so, is it possible to fix it ?

Thx for your help.
