Can't delete an account after first time login and logout

[孔祥松]

1) Ubuntu 8.04 Hardy Heron (Desktop)
2)Don't know which package does this problem belong to. Possibly the core system.

3)steps to reproduce:
1. Login into system (gnome)
2. open a terminal emulator
3. create a new account by: sudo adduser test1
4. after the new account is created, switch to a terminal by ctrl + alt + F2
5. login using the new created account test1
6. exit to logout
7. switch back to gnome desktop
8. In the terminal emulator: sudo userdel test1

expected result:
The account 'test1' should be deleted.

what happened:
The account 'test1' cannot be deleted, the system gives you an information saying that it is still logged in.
You need to reboot the system and then you can userdel the account.

This isn't a deadly critical bug, but it make me feel uneasy. Hope you guys can fix it later.

Confirming. Tentatively assigning to shadow for now.
