locale is set correctly but most app not change language

[Jens Getreu]

Binary package hint: language-selector

I only observed this on a machine that was upgraded from ubuntu 10.09 to 04/10 :

I have installed 4 language locales : English, French, German.

1. LOCALES ARE GENERATED

2. EVIRONEMENT IS SET CORRECTLY

ge@leo5:~/Bureau$ env |grep LAN
LANG=en_GB.utf8
GDM_LANG=en_GB.utf8
LANGUAGE=en_GB:fr:de:de_AT:de_BE:de_CH:de_DE:de_LI:de_LU:en_AG:en_AU:en_BW:en_CA:en_DK:en_HK:en_IE:en_IN:en_NG:en_NZ:en_PH:en_SG:en_US:en_ZA:en_ZW:et:et_EE:fr_FR:fr_BE:fr_CA:fr_CH:fr_LU:en
ge@leo5:~/Bureau$

ge@leo5:~/Bureau$ env |grep LC
ge@leo5:~/Bureau$

3. SOME APPLICATIONS CHANGE THE LANGUAGE CORRECTLY

ge@leo5:~/Bureau$ passwd
Changing password for getreu.
(current) UNIX password:
passwd: Authentication token manipulation error
passwd: password unchanged
ge@leo5:~/Bureau$ LC_ALL=de_DE.utf8 passwd
Ändern des Passworts für getreu.
(aktuelles) UNIX-Passwort:
passwd: Fehler beim Ändern des Authentifizierungstoken
passwd: Passwort nicht geändert

eu@leo5:~/Bureau$ LC_ALL=de_DE.utf8 ooffice
(it starts in German)

4. OTHERS STAY IN FRENCH (what ever the chosen language might be).

eu@leo5:~/Bureau$ LC_ALL=de_DE.utf8 dia
(dia:5881): GLib-WARNING **: A group named "gtk" is already part of this GOptionContext
(it starts in French!!!!)

5. THE ONLY LOCALE THAT ALWAYS SEEM TO WORK IS "C"

eu@leo5:~/Bureau$ LC_ALL=C dia
(dia:5904): GLib-WARNING **: A group named "gtk" is already part of this GOptionContext
(it starts in English)

I noticed the following :

At login : the language change has no effect.

Very bad workaround:
1. In language selector push the desired language on first place.
2. apply to the whole system
3. Reboot.

Still : behaviour only observed on the upgraded system.
The from scratch installed system has no problems.
