Comment 42 for bug 240437

no!chance: See bug 160862 rather. This is a know problem that is fixed in Lucid and should be fixed at some point in Hardy too. Though the original issue is that you had weird characters in your /etc/group file, nowadays users-admin shouldn't get crazy when it encounters this kind of thing.

I'm closing this report because of lack of information. There have been many changes in Lucid that mean this bug cannot happen, so that's less of an issue anyway.
