Hi.
By default, when you do a fresh install, user_account attribute for user class is not translatable but is mandatory.

This leads in a annoying case. You can probably need create a new version of your user object in another language.

A case of use could be a site with job offers, where some users could want to add their resumes in several languages.

The thing is when you create this new translated version, nothing is entered on user account, and so, validateObjectAttributeHTTPInput from ezusertype.php file will produce an error when you submit.

Any ideas?

Steps to reproduce

install a multilingual site
go to your users zone
try to make a new translation for your admin user.
