translation does not work for ‘Home’

Using the birdtips theme, translation of messages generally works, with some minor omissions.

When I click on a page, a new line appears below the header image saying

Home >> MyPage

Now, “Home” is not translated to the language set in the locale, although the code invokes a translation function:

<?php _e('Home', 'birdtips'); ?>

The file wp-content/languages/hu_HU.po does contain the translation of this string:

msgid "Home"
msgstr "Kezdőlap"

Is this a bug in the theme? How can I fix this?
