PullToRefreshListView$InternalListViewSDK9 中的 IllegalStateException

我在应用程序的两个活动中使用 PullToRefresh 库。我知道，这个库已被弃用，但它非常有用，它不仅可以处理来自顶部的刷新手势，还可以处理来自底部的刷新手势。但它有一个问题：应用程序很少因以下日志而崩溃：

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)]

这种崩溃很少发生，以至于我在几个月的频繁使用中只在我的设备上看到过一次。但我在 Google Play 开发者控制台中看到了来自用户的包含此日志的崩溃报告。

据我了解，此崩溃不是发生在我的代码中，而是发生在 InternalListViewSDK9 类的 PullToRefresh 库的代码中。这是InternalListViewSDK9的代码：

@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;
    }
}

考虑到我无法重现这个错误，如何修复它？也许有可能压制它？
