In my project I'm using plone.postpublicationhook that depends on ZPublisherEventsBackport, which in turn applies plone.app.linkintegrity's get_module_info patch on purpose. As I understand, patch is done using positional and keywords arguments (*args, **kw) which makes func_defaults equal to None.

When I'm not using plone.postpublicationhook then plone.app.linkintegrity's patch is not installed in testing environment, so no issues encountered then.
