Issue details / Repro steps / Use case background:
I have a Fragment which loads images from a dynamic list of them. If I enter the Fragment and stay until the images all load, there's not problem. If I replace the Fragment before loading of all the images is complete, I get a You must pass in non null View exception. What am I doing wrong?

Glide load line / GlideModule (if any) / list Adapter code (if any):

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View rootView = inflater.inflate(R.layout.fragment_chatholder, container, false);

        LinearLayout horizontalLayout = (LinearLayout) rootView.findViewById(R.id.chat_horizontal_layout);

        int dpConversion = (int) rootView.getResources().getDisplayMetrics().density;

        for (int k = 0; k < matches.size(); k++) {
            if (horizontalLayout != null) {
                CircleImageButton newButton = new CircleImageButton(rootView.getContext());
                newButton.setIndex(k);
                newButton.setBackgroundColor(Color.alpha(0));
                newButton.setScaleType(ImageView.ScaleType.FIT_CENTER);
                LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams
                        .WRAP_CONTENT, LinearLayout.LayoutParams.MATCH_PARENT);
                params.setMargins(0, 0, dpConversion, 0);
                newButton.setOnClickListener(this);
                horizontalLayout.addView(newButton, params);
                Glide.with(getActivity()).load(matches.get(k).getPhoto_one_url()).asBitmap().transform(new CircleTransform(getActivity())).skipMemoryCache(true).into(newButton);
            }
        }

        return rootView;
    }

Wow, I'm sorry, I was looking at the wrong fragment... Never mind.
