The strange thing is that can go to the direct link of a file.
I already tried 3.2 but the same thing there.
Has anyone an idea ?

It is indeed the &, that causes these kind of problems in the validation. It should be encoded as & amp; (without the space) by passing it trough the appropriate php function (htmlspecialchars) and settings . To get it right, changements may be needed in the core and/or the module.
