ubiquity crashed with AttributeError in reset_locale()

[jta]

Binary package hint: ubiquity

I guess ubiquity is the installer from ubuntu...
I am in the liveCD. And I opened the diskutility after I started the installer.
Diskutility refused to perform because it said daemon busy or something.
So I closed the installler...
And then I got the message
