Eep. Can you check the value of the @action hidden field in the login
form. It should be the english word Login. It looks like it's
translating things it shouldn't be.

The jinja2 template is a work in progress and the person who
contributed it has been away for some time.

I hope this is not the tip of the iceberg.

So if you know how to fix it and can add a patch that would be great.
