"load-started" on the WebKitWebView only seems to fire for the main frame.  WebKitWebFrame doesn't emit a "load-started" signal, so I don't think that can help me.

I have since been able to call webkit_web_frame_load_string() from within "navigation-policy-decision-requested".  On the first pass I didn't notice that webkit_web_frame_load_string() from with the signal handler emits second "navigation-policy-decision-requested" signal, and my naive attempt was simply blowing the stack.  If I don't call _load_string() in the second emit, it seems to load smoothly.

I still have a segfault attempting to use webkit_web_view_load_string() from within "resource-request-starting", and can provide the stack trace if it's still interesting to you.  It may not be worth investigating because there's a workaround, but that one is not a handler recursion issue, it's something more complex.
