I have been using network-config-users, but now when I try to use it, the graphical window appears for a second and then disappears. The following message is also displayed once the window disappears:

$ redhat-config-users
/usr/share/redhat-config-users/userWindow.py:73: DeprecationWarning: use GtkListStore/GtkTreeView
self.loginShellCombo.list.select_item(self.shells.index(default))
Traceback (most recent call last):
File "/usr/share/redhat-config-users/redhat-config-users.py", line 36, in ?

self.refresh_users()
File "/usr/share/redhat-config-users/mainWindow.py", line 303, in refresh_users
gidNumber = userEnt.get(libuser.GIDNUMBER)[0]
IndexError: list index out of range

Network-config-users is the graphical tool for user/group administration in gnome.
Can anyone help with this? TIA

it seems to be trying to find information on a group of users that maybe doesn't exist. hmm, have you been missing around with any groups recently? check there's nothing bizarre in /etc/group. you could always try to shoot the error by going into that python script file and inserting a simple print statement there to print the group numbers that are causing the problem. that's given that my assumption is write there of course.

Thanks for the tip. I'll check the etc/group as you suggested and post another reply with what I found. Thanks again.
