The list title and description fields that appear at mailchimp/subscribe and user/register are not translatable via i18nstrings.
The main issue is with the following two function calls:
t('@name', array('@name' => $list->name)) t('!desc', array('!desc' => $list->description))
Those will never translate anything.
List name and description appear in a few other places where they are also not translated.
