Zimbra language weird thing

[feiticeir0]

Hi !

I've just upgraded my zimbra installation from 5.0.8 to 6.0.7
(Release 6.0.7_GA_2473.RHEL5_64_20100616215237 RHEL5_64 FOSS edition)

The new version has Portuguese as a language, and in the admin console I've defined as default.

the problem lies when a user goes to his preferences, and tries to change the language, Portuguese does not appear in the languages list, only Portuguese-Brazilian...

Why portuguese is shown in the Admin console, but when a user tries to choose it as it's default language, does not appear ?

Any thoughts ?

Cheers,

Bruno
