Multiple field_collection field missing last element on translation

Hello,

I'm experiencing the following issue:

- I have a content-type "product" which has a field_collection named "features"
- features are field_collections with one image and two text fields

If I

- create a product in one language (i.e. English) with 5 features
- translate it in another language (i.e. Italian)

I get a pre-populated form with only 4 features (the last is missing)! If I add another feature to the original node the translate it again I get 5 features instead of 6... the last one is always missing!

Anyone has experienced this issue before?

Can anybody point me to where could be the problem? I'm thinking of a wrong "for" loop or something like that. Who does the pre-population of the content when translating a node? Is it the i18n module? The field_collection module? The locale module?

Any hint would be appreciated. Thanks in advance.

Regards,
Maurizio
