Howto set language for single application?

[Felix Homann <fexpop@onlinehome.de>]

Hi,

though I usually prefer to use KDE in English every now and then I would like 
to start a single application in German. Setting the LANG variable doesn't 
work, e.g. 

user:$ LANG=de_DE konqueror

still yields an English konqueror. The respective i18n packages are installed. 
Changing the language setting for the whole KDE environment does work.

Any idea?

Thanks,

Felix
