Identical emails (with mixed case) get confused in the profile page
I seem to have two email addresses attached to my profile which are identical apart from the case of some of the characters. They are both listed on the Email Addresses page. One of the emails is marked as the 'primary' address and the other has an option to 'resend confirmation'.
My account constantly says the email address is unconfirmed in the header bar.
If I click on the 'resent confirmation' link the page changes to show both email addresses as 'primary'. However, as soon as I navigate away from the page the error reappears in the header bar and the email addresses page returns to the previous state.
If I try to delete the second address it says I can't delete the primary address.
