For anyone meet this issue, please close Ubuntu Tweak and try again, in most case it will be ok.

This is caused by the unstable of Gconf-dbus.

Could you try to run Ubuntu Tweak by turning on the "debug" mode?

    ubuntu-tweak -d

This bug will be fixed after you do a system update. It is caused by gconf.
