Thanks for your report. This is very similar to bug 432964. Check that there's a file called /etc/gshadow.lock, and possibly /etc/shadow.lock, /etc/passwd.lock too; if that's the case, remove them (no risk), and retry. The problem might come from a crash while using the guest session: do you remember such a situation?
