Merge lp:~cjwatson/ubuntu/precise/casper/jackd-debconf-hang into lp:ubuntu/precise/casper

[Colin Watson]

casper-reconfigure fails when run within a ubiquity target-config hook because the environment is such that debconf thinks there's already an active frontend and so disregards the "-fnoninteractive" option to dpkg-reconfigure. Unsetting a few environment variables is enough to dispel this confusion.
