--- Comment #6 from Ryosuke Niwa <rniwa at webkit.org> ---
This appears to be caused by setupIOSWebKitEnvironment not setting __XPC_* environmental variables. Applying the following diff seems to solve this issue although trunk WebKit immediately hits a debug assertion trying to load any real web page. It can successfully load about:blank and some basic data URLs however.
