X environment

[Jan]

Hello!

I'm using Gentoo with Xfce as desktop (with GDM for login). 
In file /etc/profile.env I have line:
export LANG='en_US.UTF-8'

However for certain user I want LC_COLLATE to be
LC_COLLATE='ja_JP.UTF-8', therefore I set it in 
~user/.bashrc

The problem is that in xterm I get it set properly however when running
(for example evolution mail client) from xfce menu
LC_COLLATE='ja_JP.UTF-8' is apparently ignored. (Addresses in evolution
are not sorted properly).

Why is my bash environment and X environmet different ?

Thanks
Jan
