[webkit-dev] Disable Javascript security warnings?

Hey all,

I'm working on a web scraper that embeds WebKit directly (via pyWebKitGTK if
it matters, though I don't think my question is specific to that library).
 I'm trying to extract image metadata (domains, dimensions, location on the
page, etc) from a page, including any iframes that are embedded there.

Because WebKit already knows everything about the data I want (image
dimensions, position on page), I'm extracting content by executing
javascript via the webkit_web_view_execute_script call described here:

My javascript works when the iframes are on the same domain, but fails
(obviously) when they're not.  How can I disable the "Unsafe JavaScript
attempt to access frame with URL http://www.google.com/ from frame with URL Domains, protocols and ports must match."
error message?

I've come across the WebKitSecurityOrigin object and I've been able to
extract the host/port/protocol of my current page, but I haven't found a way
to spoof this mechanism…

I know too that Chrome has the --disable-web-security flag, but I can't
quite put my finger on what I need to do to replicate this functionality
when working with WebKit directly.

Can anyone offer a pointer or suggestion?

Thanks so much!
