full crash report

Hi.
Since iOS 10 came out, we started to see several crashes in WebKit's IPC network component. I didn't see it this crash in iOS 9 if I recall.
As known, WKWebView renders and loads content in a separate process, thus content loading problems only cause the WKWebView process to crash and we get a delegate call to our app.

In this case, the app itself crashed as well (after we got to see for a split second that the wkwebview content process crashed) in thread 0.

This is the stack trace of thread 0: (attached is a full stack trace)
