attempt to re-open an already-closed object when using loaders

I am using loaders to show the result of a query from database. The database is for storing the data of a download manager which is really similar to the download manager of android.

I am using the support library version of loaders and fragments (rev 19). Here's the loader callback methods:

    @Override
    public Loader<Cursor> onCreateLoader(int arg0, Bundle arg1) {
        QueryArgs args = getQueryArgs();

        cursorLoader = new CursorLoader(getActivity(), args.uri, args.projection,
                args.selection, args.selectionArgs, args.sortOrder);

        return cursorLoader;
    }

    @Override
    public void onLoadFinished(Loader<Cursor> arg0, Cursor c) {
        if(adapter == null){
            adapter = new CustomAdapter(getActivity(), c, 0);
            lv.setAdapter(adapter);
        }
        else
            adapter.swapCursor(c);
    }

    @Override
    public void onLoaderReset(Loader<Cursor> arg0) {
        if(adapter != null)
            adapter.swapCursor(null);
    }

I don't close cursor anywhere in my code as the loader is responsible for that. But here is the stack trace I get on some devices in my developer panel:

java.lang.IllegalStateException: attempt to re-open an already-closed object: SQLiteQuery: SELECT _id title description total_bytes current_bytes status lastmod _data FROM downloads WHERE (is_visible_in_downloads_ui != '0' AND deleted != '1') ORDER BY lastmod DESC LIMIT 50

Can someone help me understand what's going on here?
