I tried accessing the users and groups panes through the hat menu, and they didnt come up.

I then tried executing the redhat-config-users command and it returned the following:

/usr/share/redhat-config-users/redhat-config-users: line 4: 1992 Segmentation fault /usr/bin/python2.2 /usr/share/redhat-config-users/redhat-config-users.py

The number before the segmentation fault changes during each iteration, but the line number is still the same.
Any clues as to what could be causing this ?
