It seems there is a problem in the french localization files:

in messages.inc:

$messages['nomessagesfound'] = 'Auncun message trouvé dans cette boîte aux lettres';

should be:

$messages['nomessagesfound'] = 'Aucun message trouvé dans cette boîte aux lettres';

There is still a problèmes with some special characters display for the message count display on the upper right of the message tab:

Messages 1 ? 2

It should be : Messages 1 à 2

Thanx for the changes. Roundcube is now and still the best webmail app.

Keep on.
