Comment 4 for bug 923474

Just as a note, the langpacks are not updated because the french community didn't test any of the proposed updated since oneiric: https://wiki.ubuntu.com/Translations/LanguagePackUpdatesQA

it seems like the french team could do a call for help testing those for the next round, testing should be easy enough it's basically installing the update, checking that things still look fine and update the wiki
