yes, that is a problem. has your new zealand language selection ever been a problem, before (from "esktop.en_NZ.UTF8.cache...")?
anything you may have done that could have influenced this, by chance?
my first reaction would be to try typing this:
based mostly on reading this:
sudo dpkg --configure language-selector-common
or you could give this a shot:
dpkg: dependency problems prevent configuration of language-selector:
language-selector depends on language-selector-common (= 0.6.7); however:
Package language-selector-common is not configured yet.
sudo dpkg-reconfigure language-selector-common
if that doesn't do it, i'd probably open a thread specifically with that error message, and link back to this thread.
(to ensure people really good at fixing dpkg problems see it and can help you. i am very mediocre at that.)
