Translations don't work in Additional Software
Originally created by @xin on #16601 (Redmine)
In Tails in French, the text is in English in the Additional Software
application and in notifications about Additional Software.
All this content is tranlated in po/fr.po. This bug may be present since
3.9 release.
I also test in Spanish, same problem.
