Description of problem:
When I open Konsole, I see perl complaing missing locale:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "en_US.UTF-8:en_US:en",
        LC_ALL = (unset),
        LC_PAPER = "it_IT.UTF-8",
        LC_ADDRESS = "it_IT.UTF-8",
        LC_MONETARY = "it_IT.UTF-8",
        LC_SOURCED = "1",
        LC_NUMERIC = "it_IT.UTF-8",
        LC_TELEPHONE = "it_IT.UTF-8",
        LC_MESSAGES = "en_US.UTF-8",
        LC_IDENTIFICATION = "it_IT.UTF-8",
        LC_COLLATE = "en_US.UTF-8",
        LC_MEASUREMENT = "it_IT.UTF-8",
        LC_CTYPE = "en_US.UTF-8",
        LC_TIME = "en_US.UTF-8",
        LC_NAME = "it_IT.UTF-8",
        LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

 

Version-Release number of selected component (if applicable):

MGA3Beta1 live dvd kde

How reproducible:
installing MGA3, I choose

locale=en(US) (default choise)
time fuse = Rome
keyboard=italian 

at the end of installation, 
the installer asks to remove unnecessary packages,
and I choose to remove them

when the system starts, in konsole I can see every time I hit enter or some command:


[tom@localhost ~]$ rpm -qa | grep locale
locales-2.16-3.mga3
locales-en-2.16-3.mga3

easy to fix, 
but probably the italian locale was removed at the end of the installation
as 'unuseful package'
