How about just not calling this at all if we're uninitialized? (seems like this
would probably apply to the other account mapping methods above too, right?)

[fgorski, 2014/11/07 22:57:02]

tracker does not call the other methods. GCMAccountMapper does it, and it is
typically shutdown properly.
as for checking the state, check this out:

void GCMClientImpl::Stop() {
  DVLOG(1) << "Stopping the GCM Client";
  weak_ptr_factory_.InvalidateWeakPtrs();
  device_checkin_info_.Reset();
  connection_factory_.reset();
  delegate_->OnDisconnected();
  mcs_client_.reset();
  checkin_request_.reset();
  // Delete all of the pending registration requests, whithout telling the
  // consumers.
  // TODO(fgorski): Perhaps we should make a distinction between a Stop and a
  // Shutdown.
  STLDeleteValues(&pending_registration_requests_);
  state_ = INITIALIZED;
  gcm_store_->Close();
}

specifically last two lines...
This might be a genuine bug actually. But I'd rather not fix it as part of this
patch.

Okay, maybe file followup bug?
