please write ps version, this module (1.0.4 latest) version and ps_emailsubscription module version. because as I see this bug is possible only on 1.7
to temporary disable this part of functionality just unhook this module from actionNewsletterRegistrationBefore hook
just tested on 1.7.8.11 and 8.x ps and not found any bug with newsletter
