Simplenews condition results in double email I've got a simple rule sending a notification email to site admin on the event 'A user has been subscribed'.

I'm however getting 2 emails on a signup. Any idea why and how to fix so the admin only gets notified once on each signup?

@Kristoffer Rom, I've just tested and I've got the same duplication.
So, I suggest you create such notification rule based on:  


"After saving new user account" event.
"Send mail" action from "System" actions group.
