Content translation is showing inactive languages

Hello i18n Community !

My scenario is the following:

I have a multilanguage site with SPANISH as the main language and 4 other languages including english. Native english language is inactive and I've created a new english, becouse of some problems related to spanish being the main language.

The site is working great (thanks to you guys!) but when clicking on the "Translate" tab for translating content, in the list of translatable languages English is showing up twice (and one is INACTIVE!). Am I missing something?

I've crawled through drupal site and found nothing related to this problem. I'm afraid deleting the native english language will cause some trouble so I don't want to try this before asking !

Thanks a lot and keep up the good work !
Leandro.
