Translation of quicktabs got Mixed up with other qucktabe sets.

This bug was tracked down, that it dose sort tabs in the right woay..
But Translation of Tab's Title will mix with other Tabs.

Bug Location :
the function quicktabs_translate dose not use t() it dose use the i18n_string for each user.
and function translateString will do as well.
tried to fix it using t($string) it worked.

I'm looking to override quicktabs_translate as a temp fix for this bug.
at hook_quicktabs_alter function to use t() will not fix this. as values will be translated as well using quicktabs_translate

function hook_quicktabs_alter(&$quicktabs) {
  foreach ($quicktabs->tabs as &$quicktab) {
    $quicktab['title'] = t($quicktab['title']);
  }
}

I can not find the right theme hook to override.
