Comment 2 for bug 553120

I think this might not be a bug related to translations or incomplete translations.

I think the problem might simply be that the test was done with an English installation in which the locale was then changed to French.

This should in theory work just as well as an installation in which the language has been chosen at the start, but I believe due to bug 553162 parts of the desktop might be shown in English. So I think it's better to test translations with full installations started in the given language.
