Kubuntu Feisty upgrade from Alternate CD fails

[Andy Bovett]

I attempted to upgrade a Kubuntu Edgy system via:

gksu "sh /cdrom/cdromupgrade"

(As per http://www.ubuntu.com/getubuntu/upgrading)

The upgrade tool crashed with the following error:

Traceback (most recent call last):
  File "/tmp/tmp--6CXQ/DistUpgradeViewKDE.py", line 72, in update
    self.progressbar.setProgress(percent)
AttributeError: KDECdromProgressAdapter instance has no attribute 'progressbar'
