Description of problem:
redhat-config-network-cmd claims to be "Python network configuration
commandline tool" but requires a working Xserver to function. When DISPLAY
is not set, or Xserver is not reachable, or refuses connection, the tool
crashes.

Version-Release number of selected component (if applicable):
redhat-config-network-0.6.1-1

How reproducible:
Always

Steps to Reproduce:
1. unset DISPLAY (or run the tool from console).
2. redhat-config-network-cmd --help

	

Actual Results:  No display information -- gtk_init not called
gdk_imlib ERROR: gdk has not connected to the display

Gtk-WARNING **: cannot open display: 


Expected Results:  redhat-config-network-cmd - Python network configuration
commandline tool

Usage: redhat-config-network-cmd -p --profile <profile>


Additional info:

I think it is important to have profile switchin functionality not only
when using graphics interface but also in scripts/command line. I have
impression it should not be difficult.
