Comment 1 for bug 857514

easy way to reproduce on Oneiric up to date:
1. remove "Ubuntu Software Center" from your gpg key (using seahorse for instance)
2. ensure oneconf is stopped: oneconf-query --stop
3. open software-center
4. click on File -> Sync between computer
-> there is an sso login_or_register() dbus command req. starting the service
Note as well that oneconf-service is started as well
5. don't file the dialog, wait 20s (oneconf-service is independently making a sso request find_credentials() 20s after starting)
-> once oneconf-service made its request, the ubuntu-sso-login process will close, making the dialog closing.
