How to set language default for Gnome applications

[Ambrogio De Lorenzo]

Hi all,
I'm using KDE on Fedora 9, but I can't select a default language for
some gnome applications, such evolution or pidgin for example.

Firefox is correctly setup to Italian, but evo and pidgin are in
english.

I installed system-config-language and used it to setup to Italian
language, but nothing appens on gnome-apps (even after restarting the
desktop).

There are other setting panel (specific for gnome apps) to instruct them
to be in Italian?

TRnx to all,
 Ambrogio
