[Bug 448768] [NEW] Setting the language in KDE does not set env vars

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Release: Ubuntu 9.04
KDE 4.2.2

Setting the language in the KDE4 (Kubuntu 9.04) system settings does not change the related env vars.
KDE apps then have the new language, but e.g. firefox does not.  It's still shown in the system's default language,
in my case german.  After disabling the firefox language and xulrunner add-ons (except the one desired), firefox is in english/C.

Expected behaviour: After setting the user's language (not locale) all programs should display their menu, messages etc. accordingly.
For most people it is simply not possible to fix that in the shell profile.
----
Workaround: Set the LANG variable:
danish at paul-mac:~$ echo $LANG
de_DE.UTF-8
danish at paul-mac:~$ export LANG=da_DA.UTF-8
danish at paul-mac:~$ firefox&
[1] 18547
danish at paul-mac:~$
(process:18547): Gtk-WARNING **: Locale not supported by C library.
        Using the fallback 'C' locale.

(firefox:18547): Gdk-WARNING **: locale not supported by C library
