How to trace strange Network calls in Google Chrome?

In the developer tools, in a web app I'm working on, I'm getting a rather strange error in the console:

'GET data:'

That's it. No stack trace or anything. It is a failing network call. It shows up in the Network tab:

Request URL: data:

Request Headers

Referer: http://localhost/test开发者_StackOverflowapp/

User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.100 Safari/534.30

No error in Firefox/Firebug. Would be nice to figure out what line of HTML/Javascript caused Chrome to attempt to execute this specific request.

In the Network tab, hover over the file name of the initiator and you should find the caller in the stack trace.

Found a related Chrome bug tracker issue: http://code.google.com/p/chromium/issues/detail?id=86286

So it looks like web developers are out of luck for tracing network request sources until these issues get resolved. Both issues require their underlying engines to be modified. So Firefox and Webkit first have to support the feature, then Firebug and Chrome can, respectively and in turn, support the feature. New versions of both browsers (and plugin) need to be released. And it sounds like it won't be easy to implement.
