Opt-out link is broken in multi-lingual CiviCRM / non-English

In multi-lingual CiviCRM, when a recipient of a mailing tries to opt-out, and the opt-out link was in another language than English, the user will fall on a "DB error: syntax error".

Example link:
http://www.example.org/fr/civicrm/mailing/optout?reset=1&jid=247&qid=419319&h=0cf74e6a6502554f

This is the SQL query/error:

[debug_info] =>
SELECT civicrm_group_fr_FR.id as group_id,
civicrm_group_fr_FR.title as title,
civicrm_group_fr_FR.description as description
FROM civicrm_group_fr_FR
LEFT JOIN civicrm_group_contact
ON civicrm_group_contact.group_id = civicrm_group_fr_FR.id
WHERE civicrm_group_fr_FR.id IN ()
AND civicrm_group_fr_FR.is_hidden = 0
AND (civicrm_group_fr_FR.saved_search_id is not null
OR (civicrm_group_contact.contact_id = 48950
AND civicrm_group_contact.status = 'Added')

)

AND civicrm_group_fr_FR.is_hidden = 0
