What are miscellaneous bindings? and why are they giving me a port error?

Question

I am getting this error, that seems to have no negative effect on anything, but still.. why?

chrome console :

Port error: Could not establish connection. Receiving end does not exist.                                 miscellaneous_bindings:235
    chromeHidden.Port.dispatchOnDisconnect

You don't have to worry about those. They do not affect your own code. They originate in one of your Chrome extensions. This usually happens when an extension is trying to establish a connection to a local file (for instance when using the file: protocol).
