Hi, Got a problem with modifing user accounts.

[aPoC]

Hello.
This is my first time I'm using a mailing list, and I hope i won't do
anything bad.

Well, as the title says, I can not delete a user. (the username
disapears from the list, but after restarting 'Users & Groups' It's
there again).

My Distribution is Linux Ubuntu Karmic Coala (9.10 i think).
I've got in total 2 users, 'lordkilla' and 'apoc'.
