Localization: some string doesn't get translated

Hi.
I've a weird problem with my Cake (2.0.6) app, where some strings get translated and some don't.
Source language is Eng, I added localization for Ita.

This is the view file login.cpt:
echo $this->Form->submit(__('Login'));
echo $this->Html->link(__('Sign Up'), array('controller'=>'users','action'=>'add'), array('class' => 'register')).'<span style="float:left;clear:none;color:#999;padding:4px 0 0 4px;">';

And this is an extract from Locale/ita/LC_MESSAGES/default.po:

#: View/Elements/login.ctp:17
msgid "Login"
msgstr "Entra"

#: View/Elements/login.ctp:18 View/Elements/right_navigation.ctp:5
#: View/Elements/right_navigation_home.ctp:4 View/Users/add.ctp:60
msgid "Sign Up"
msgstr "Iscriviti"


On the view I get "Entra" and "Sign Up".
I cleared out the cache but no change. I checked the cache file after the first reload and I can find the "Entra" string but NOT the "Iscriviti" one, so it seems it's not even taken into account.
The .po file doesn't seem to be wrong in syntax.
Any clue?
thanks
