bug#25738: 25.1; Emacs Network Client (ENWC) problem when non-wired

[Live System User]

Hi,

  There appears to be an unhandled condition with the Emacs Network Client
  (ENWC) in the Gnu ELPA when you don't have a wired connection (and
  only have wireless available) and thus no "eth0" device which ENWC
  then uses for some subsequent D-bus operations:

Debugger entered--Lisp error: (dbus-error "No device found for the requested iface.")
  signal(dbus-error ("No device found for the requested iface."))

I'm unable to reproduce this bug now -- enwc-setup queries for an
interface name, and the enwc-nm-setup function doesn't seem to exist.

Are you still seeing this problem?
