Comment 4 for bug 349453

Yeah, should not be too hard to fix (i.e. refuse to remove logged in users), for the next Ubuntu version I guess.

Note that if you can't remove a user that is not currently logged in *and* you're using a completely up-to-date (as of today) Karmic system, then it's another bug that I'd really like you to report separately. And BTW, the errors with blank screen may not be related at all, there's a bug with newly created users and compiz.
