Comment 3 for bug 1582824

Actually, after investigating the situation (though unfortunately, I failed to reproduce this bug), I'm not sure that we should cahnge something in Online Accounts here.
The authorisation prompt does not appear automatically: it only appears when a client invokes the exec() method of the OnlineAccountsClient::Setup object (or the QML equivalent). When online-accounts-service receives such a request, it either initiates the account creation (if there isn't yet an account of such type) or prompts the user to grant access to the existing account.

What I believe is happening here, is that for some reason the client is making the account request twice: the first time, we start the account creation; the second time, the prompt is shown.

I will still keep the bug active, because we might want to be more robust and handle bogus requests more gracefully, but I think we have to first find out why we are getting to requests in the first place.
