This bug has been fixed in later versions; I can no longer reproduce it with 1.20.1.
jujumanage@macon:~$ juju bootstrap
WARNING ignoring environments.yaml: using bootstrap config in file "/home/jujumanage/.juju/environments/maas.jenv"
ERROR environment is already bootstrapped
jujumanage@macon:~$ juju stat
However given the potential for data loss, I'd strongly suggest that we either SRU 1.20.1 or just the relevant patch to Ubuntu 14.04.
