I was browsing the evo market and when i clicked on one of the orders it gave me this weird yellow page. I checked it's source and saw that it was an xhtml error. Which was in the file neterror.xhtml which is part of chrome, I looked up that file and saw it made a direct http connection shown in the picture: http://anony.ws/image/DHw5
This means that an http connection is created and since its client side it will give away your real ip. It can be used as a way to deanonymize tor users. This needs to be fixed...
There is no direct http connection in that file. Those are all local files stored on your computer. The w3 "link" just specifies that its an XML name space and not HTML, it doesnt connect anywhere.
