Autoupdate does not install translation files

[sirzooro]

WP autoupdater does not install translation files - at least when I tried to convert my english WP install to Polish.

Steps to reproduce:

• install WP (English version);
  
• add define('WPLANG', 'pl_PL'); to wp-config.php;
  
• open /wp-admin/update-core.php page and install WordPress with pl_PL translations.

For some reason updater does not create wp-content/languages directory and does not copy translation files.

As I recall, this worked in the past (for sure on some last WP 2.x versions), but cannot tell when it stopped working.

What file does it say it's installing on the upgrade/re-install process page?

And by file, I mean't this zip file:

Downloading update from http://downloads.wordpress.org/…

Confirmed with ru_RU as well.

Downloading update from http://ru.wordpress.org/wordpress-3.2.1-ru_RU.zip…

Message for pl_PL is similar:

Downloading update from http://pl.wordpress.org/wordpress-3.2.1-pl_PL.zip…

Cheers, I'll take a look under the hood tomorrow and see what's going on. I have a feeling this might be caused by the locale_package variable not being set when you install the way you have.

For anyone who comes across this bug, create your wp-content/languages/ folder manually, and then perform the update, the language files will be loaded then.
