Just for an update (though I am not quite sure anyone care here), the french domain name is not in the hand of OVH but quite certainly of a cybersquatter (in relation with OVH).
The phone number he offered for registration is not valid (it is normally mandatory, but the phone number does not exist).
The mail address is of a rather "special" profile : blaguekoihoo@aol.com (blague means joke in french).
We can't understand how he could register, since the .fr domain can only be registered by a firm or an organisation, which was why we had to wait till the association will be created... in possibly 2 weeks from now :-(
If it had been squatted by a firm, we could have thought of using "bad press" to negociate with them. With a private person... well, we might have only the legal path.
In any cases, Notafish has volunteered to get information on the matter.
She send yesterday the person an email.

For now, the wikipedia.fr is not redirected anywhere. We'll keep hope it won't be used for nazi propaganda, hard porn or worse, a biaised encyclopedia named wikipedia :-(
