IllegalStateException в PullToRefreshListView$InternalListViewSDK9

Я использую библиотеку PullToRefresh в двух действиях своего приложения. Я знаю, что эта библиотека устарела, но она очень полезна и может обрабатывать гены обновления не только сверху, но и снизу. Но у него есть проблема: приложение редко вылетает с таким логом:

java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. [in ListView(16908298, class com.handmark.pulltorefresh.library.PullToRefreshListView$InternalListViewSDK9) with Adapter(class android.widget.HeaderViewListAdapter)]

Этот сбой происходит так редко, что я вижу его на своем устройстве только один раз за месяцы частого использования. Но я вижу отчеты о сбоях с этим журналом от пользователей в консоли разработчика Google Play.

Насколько я понимаю, этот сбой происходит не в моем коде, а в коде библиотеки PullToRefresh в классе InternalListViewSDK9. Вот код InternalListViewSDK9:

@TargetApi(9)
final class InternalListViewSDK9 extends InternalListView {

    public InternalListViewSDK9(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected boolean overScrollBy(int deltaX, int deltaY, int scrollX, int scrollY, int scrollRangeX,
            int scrollRangeY, int maxOverScrollX, int maxOverScrollY, boolean isTouchEvent) {

        final boolean returnValue = super.overScrollBy(deltaX, deltaY, scrollX, scrollY, scrollRangeX,
                scrollRangeY, maxOverScrollX, maxOverScrollY, isTouchEvent);

        // Does all of the hard work...
        OverscrollHelper.overScrollBy(PullToRefreshListView.this, deltaY, scrollY, isTouchEvent);

        return returnValue;
    }
}

Как исправить эту ошибку, учитывая, что я не могу ее воспроизвести? Может быть, его можно подавить?
