RxPaparazzo: Memory Leak Media Scanner Connection

Has anybody encountered that LeakCanary is complaining about memory leaks? This happens when rxPaparazzo is used on an Activity, when used on fragment I don’t see any leaks. Below is what I am using the take either a picture or retrieve from gallery.

compositeSubscription.add(RxPaparazzo.takeImage(this)
                   .size(new CustomMaxSize(900))
                   .usingGallery()
                   .subscribeOn(Schedulers.io())
                   .observeOn(AndroidSchedulers.mainThread())
                   .doOnError(Timber::d)
                   .subscribe(response -> {
                       if (response.resultCode() != RESULT_OK) {
                           response.targetUI()
                                   .showUserCanceled();
                           return;
                       }
                       response.targetUI()
                               .loadPicture(response.data());
                   }));
