Front page multilingual

Hello everyone,

I have a problem. I have a website with Drupal 5.6 and i18n 5.x-2.2. The website has two front pages:

node/1 -> inicio -> Front page in Spanish.
node/2 -> home -> Front page in English.

Also, in my primary links I have a button called Inicio/Home depending on the selected languaje.

Finally, my default front page was "inicio".

When I chose English language everything appeared in English, OK, but, if then I click in Home (in breadcrumbs) or in the name of my website, I always went to my front page in Spanish.

I followed this thread to fix this:
http://drupal.org/node/70547

So I added to my settings.php file the site_frontpage in the i18n_variables array. My default front page is now multilingual.
Then I selected Spanish and set the default front page to "inicio".
Then I selected English and set the desault front page to "home".

But I still have the same problem, being in English, when I click in Home in breadcrumbs I go to my Spanish front page. In the link I said before it's said that with Drupal 5.x this problem is fixed, so, any of you know what could be happening to me?

Thank you very much.
