Bug description:
  Stable update justification:

  Impact: Due to incorrect permissions on /var/cache/debconf/config.dat, the first upgrade using update-manager may fail.  Other package management frontends that use aptdaemon may also fail on the first attempt.
  Development branch: I've fixed this in ubiquity 2.7.11 in oneiric by adding the --config=Mode:0644 option to its debconf-copydb invocation.
  Patch: https://bazaar.launchpad.net/+branch/ubiquity/revision/4769
  TEST CASE: See comment 17.  Also check the permissions on /var/cache/debconf/config.dat; they should be 0644 (-rw-r--r--), but this bug caused them to be 0600 (-rw-------).
  Regression potential: This change only affects new installations, not upgrades.  Any problems should be exposed quickly as part of milestone release / point release testing.  Although no point releases of 10.10 or 11.04 are planned, I'd like to upload this change there anyway to help out people building customised images.
