For fields which are not marked as required, uniqueness should only be checked when the field is populated.

I think this was intended by this line (in unique_profile_field_validate())
if (isset($form_state['values'][$ufids_name])) {
but the line actually needs to be
if (isset($form_state['values'][$ufids_name]) && !empty($form_state['values'][$ufids_name])) {
