Hi,

I'm trying to deal with this problem for few days but now I surrender. Few day ago I've noticed that some of my programs (xmms, aptitude, nano etc.) are in english, weird thing is that I use polish locale from the beginning. I also cannot change language in kcontrolcenter. It's quite annoying that it doesnt work as it should be To make everything clear:
in /etc/environment I have: LANG="pl_PL.UTF-8"; LANGUAGE="pl_PLl" locale generate without any error and dpkg-reconfigure locale doesn't return any error. Same thing is for ISO-8859-2. I've already done this for 1000 of times and result is still the same - English.

Maybe you know what is the problem ??

I don't know how locale works. Not really. Is it possible that you have English versions of the software?

The latest Thunderbird persists in displaying dates in the American fashion mm/dd/yy, regardless of my locale settings. I have had to use a script to launch Thunderbird and the script contains an export command prior to the line containing the executable.

EDIT: Adding .UTF-8 to my LANGUAGE setting plays havoc with some characters. I now have it added only to the LANG setting where it seems to do no harm.

And what do you have in ~/.profile (which is sourced after so might override /etc/profile)
?
Also what version of debian are you running?

I would also suggest that you give a try to the package language-env
