The bug that appears in the Console when inspecting the Remote Web Inspector when a site does not work in the Remote Web Inspector

Sometimes the Remote Web Inspector does not work for some sites, just displaying a blank white box where the DOM Tree should be. None of the assets/resources for that site load either (they are shown in the resources panel but just hang when trying a specific one). I have noticed that this seems to happen more on sites that are hosted locally, especially when using a port (i.e http://localhost:1234). I have been developing locally with Jekyll (https://github.com/mojombo/jekyll), which uses the port 4000 by default and this is one of the primary examples I have. 

When a site does not work, I have inspected the Web Inspector and the error is always the same: http://cl.ly/OCyH. I have tested this on an iPad 2 running iOS 6.1.3 and an iPhone 4S running iOS 6.1.3 and it is replaceable on both although occasionally the site will work, although it's often very slow and annoying.
