I've pushed a repair for the crash, which was due to a bug in the new macro expander.
The "boris/hypertext-browser/http/head.rkt" module creates a pattern of binding and shadowing that had never been exercised before --- at least not in code saved in bytecode form. (It took me much longer to construct a test case that navigates the same path than to fix the bug.) I think that `scribble/srcdoc` is a key step in making "head.rkt" trigger the expander bug, so if a workaround is needed, probably it involves avoiding `scribble/srcdoc`. Thanks for the report!
