Currently I'm working on a 6-language website and all content obviously needs to be translated, including menus. For this, I have enabled i18n_menu and i18n_select (as I had a little experience on the latter regarding this issue), translated the originally French node to English, and both menu items show up when I go to English translation of the node. Any ideas?
There are several discussions on drupal.SO about this, including this and this one on drupal.org; but none seemed to resolve my issue.
