KDE country region and language

[Adam Hardy <adam.ant@cyberspaceroad.com>]

In KDE, I have a problem configured the country/region and language 
settings.

KDE is obstinately using US English as the language, even though my 
region says United Kingdom. After all the debate about whether colour or 
color is correct, I thought I should be able to configure it.

There is an 'Add Language' dropdown in the dialog box, but this has only 
the one option - US English.

Shouldn't there be a way of telling KDE to give me more options to add?

Surprisingly I can't find anything useful on the KDE sites or forums 
about this, apart from references to /etc/environment, which looks correct:

LANGUAGE="en_GB:en_US:en_GB:en"

LANG=en_GB


Any Brits out there running KDE with UK English?

Thanks
Adam
