Custom Taxonomy permalink translation

Hi support,

I got an issue with my custom taxonomy permalink in the language switcher, actually i use this technique to translate my custom taxonomy slug in the taxonomy registration function :

'rewrite' => array( 'slug' => __('my-custom-slug', 'mytextdomain') )

But the link generated by the language switcher will not use the correct taxonomy slug, for example if i am on the english version i’ll have http://fr.myblog.com/my-custom-slug/mon-term instead of http://fr.myblog.com/mon-slug-personnalise/mon-term for the french link.

Have you got a solution for that ? Or is it a natural limitation due to WordPress ?

Sincerely
