Description of problem:
there is a segfault in redhat-config-network-gui and
redhat-control-network. Those files are python file. I don't know how
to know which program segfaults nor how to have a backtrace. I am not
even sure that these segfaults are related, but I guess so.

I have an adsl usb modem sagem fast800, I use the drivers provided by
the project
http://sourceforge.net/projects/eagle-usb/
(there was another site, but I can't reach it now).

redhat-config-network-tui seems to work.

I understand that it isn't enough informations, but I don't know how
to add more (I know some programming languages, but not python).
 
Version-Release number of selected component (if applicable):
redhat-config-network-1.3.10-1

How reproducible:
always

Steps to Reproduce:
1. run the commands
2.
3.
  
Actual results:
[root@localhost root]# export LANG=C;  redhat-control-network
Segmentation fault
[root@localhost root]# export LANG=C;  redhat-config-network-gui

Leads to a pop up:
Application "redhat-config-network" (process 8544) has crashed
due to a fatal error.
(Segmentation fault)

Expected results:
Something else
