[translations] A couple of untranslated strings in 5.x core

Hello people,

I've noticed a couple of untranslated strings in Drupal 5.1. Here's the procedure I've followed:

1) Installed a fresh Drupal 5.1. 2) Enabled all modules. 3) Added the greek language as a secondary language in Localization settings page. 4) Imported the translated .po file for greek [the translation is 100% complete, the Localization settings page reports 2431/2431 (100%)]. 5) Changed the site's default language to greek.

In the navigation menu in left, under Create content, the names and the descriptions for the Page and Story content types are untranslated and remain in English.

Is this a bug? Should I open an issue about this?
