i have forgotten to mention, that adding users didn't f##k up the system in any way. it's just the gui app not showing anything.
and i already found out why was that in my case (i wish if all things could be fixed this fast! :) in my case, my "Real Name" contained national characters, which showed up wrong in the /etc/passwd file. the system obviously didn't know how to handle these characters or something. after editing the passwd file manually, the gui app started to work again. -- [users-admin] [HARDY] erasing /etc/passwd and /etc/groups when failing to load configuration https://bugs.launchpad.net/bugs/234473 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
