Multiple e-mail field required error message

Hi.

I'm creating one project and one of requirements is multiple e-mail field in node form, so when tested this field I found problem.
When I'm using this field as single value without "Add more" option, everything is working great, but when change to multiple value field and check that it's required, than after saveing empty node, it returns wrong required error message: "field is required." instead of "E-mail field is required.".

Checked this problem with fresh Drupal 7.22 with Email Field 7.x-1.2
