刚刚发布了一个新版本的应用，它已经开始崩溃了
致命异常：NSInvalidArgumentException * - [__ NSDictionaryM setObject：forKey：]：key不能为nil
问题似乎在于在后台线程上调用-[NSExtension _reallyBeginExtensionRequestWithInputItems:listenerEndpoint:completion:]，后者又试图设置一些nil字典键......

我遇到的问题是应用程序没有任何扩展 - 所以我想知道为什么调用这个方法的原因。我可以在this post中找到这个方法的唯一参考，但这没什么帮助。
应用使用在很多版本之前拥有共享和照片编辑扩展程序，但这些已经删除很久了。
根据Crashlytics的说法，这似乎发生在大约十分之一的应用会话中。我在发布时已经看过它了，所以我假设它也在发生在其他地方 - 但除此之外我无法重新创建。
有关可能导致此问题的任何想法？

在生产应用程序中添加一些日志记录似乎表明在呈现UIIMagePickerController
然后我设法捕捉到一个异常，这似乎证实问题确实存在于图像选择器......
