При повторном выполнение запроса не отлавливается исключение

Создаю запрос вот таким образом. Если после того, как вызвался showError(). вызвать doRequest() еще раз, то ошибка не отловится и все упадет. Пробовал задавать глобальный error хэндлер. Но это не помогает.

private void doRequest() {
    Subscription subscription = AppObservable.bindFragment(this, Observable.create(new Observable.OnSubscribe<List<Object>>() {
        @Override
        public void call(Subscriber<? super List<Object>> subscriber) {
            //тут происходят какие-то сетевые запросы
            //если все плохо, то кидается исключение
            //это исключение и не отлавливается при повторном выполнении этого кода
            subscriber.onNext(new ArrayList<>());
            subscriber.onCompleted();
        }
    }))
            .flatMap(getStringSelector(), getMapFunction())
            .subscribe(new Action1<Boolean>() {
                @Override
                public void call(Boolean aBoolean) {
                    if (aBoolean) {
                        showOk();
                    }
                }
            }, new Action1<Throwable>() {
                @Override
                public void call(Throwable throwable) {
                    showError();
                }
            });

    CompositeSubscription subscriptions = new CompositeSubscription();
    subscriptions.add(subscription);
}
    @NotNull
    private Func2<List<Object>, List<String>, Boolean> getMapFunction() {
        return new Func2<List<Object>, List<String>, Boolean>() {
            @Override
            public Boolean call(List<Object> objects, List<String> stringList) {
                if (objects.size() == 0 || stringList.size() == 0) {
                    throw new RuntimeException("");
                }
                return true;
            }
        };
    }

    @NotNull
    private Func1<List<Object>, Observable<List<String>>> getStringSelector() {
        return new Func1<List<Object>, Observable<List<String>>>() {
            @Override
            public Observable<List<String>> call(List<Object> objects) {
                if (objects.size() == 0) {
                    return Observable.error(new Exception("some text"));
                }
                return Observable.create(new Observable.OnSubscribe<List<String>>() {
                    @Override
                    public void call(Subscriber<? super List<String>> subscriber) {
                        subscriber.onNext(new ArrayList<String>());
                        subscriber.onCompleted();
                    }
                });
            }
        };
    }     

UPD: лог ошибки. Собственно исключение Caused by: retrofit.RetrofitError: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: должно быть отловлено и отлавливается при первом вызове
