Binary package hint: ubiquity

At line 991 in the ubiquity install.py will likely to make the installer crash, since the declaration of DebconfError is not defined. It's a #NameError and will likely to cause the crash on most hardware configurations. see (http://kubuntu.org/~jriddell/tmp/syslog-powerpc)

I think the solutions are to change the DebconfError: to debconf.DebconfError:
Here's the lines involving the NameError syntax.

             participate = self.db.get('popularity-contest/participate')
             self.set_debconf('popularity-contest/participate', participate)
- except DebconfError:
+ except debconf.DebconfError:
             pass

         self.chrex('mount', '-t', 'proc', 'proc', '/proc')
