Comment 1 for bug 1293837

Well it does not require 1) nor 2) nor 3), but that 4) I have not seen before.

Did you modify the script in any way? See https://bugs.launchpad.net/kicad/+bug/1248627

That should solve it, I just tested it (the last patch) on an ubuntu 13.10, where bzr whoami and bzr lp-login fails, that is they are not defined.
