Comment 16 for bug 316756

To reproduce:

1) Verify that /etc/login.defs contains 3 tabs between the key + value of UID_MIN and UID_MAX.
2) Save a copy of /etc/login.defs
3) Launch System->Administration->Users and Groups
4) Click the Unlock button, enter your admin password
5) Click the Add User button. Add a user called 'test' with bogus data. Don't touch the Contact, User Privileges, or Advanced tabs. Hit OK in the dialog to create the user.
6) Diff /etc/ogin.defs with the copy you saved. The diff should show that whitespace has changed for the UID_MIN and UID_MAX fields. Instead of 3 tabs in those fields, there will be a single space

Reproduced on my Jaunty Beta system. gnome-system-tools version is 2.22.2-0ubuntu2.
