When attempting to inspect a network-stream of underlying type SB-SYS:FD-STREAM I always get the following error:
Error: The value NIL is not of type PATHNAME.
I wrote a small patch to swank-fancy-inspector to ignore errors coming from accessing the pathname slot and not render the action link (visit file and show current position) when we do not have a pathname.

Made swank-fancy-inspector NOT error when attempting to inspect network streams (due to their pathname being unbound)
