image field "Add a new file" doesn't appear when an image is uploaded in Profile2 when field translation module is active

@joachim: Thank you for your answer. Does it ? I tried the last git and the problem remains the same.
Did you try to upload a file?

The add a new file is displayed first, but is not displayed again after the image has been uploaded, if you don't hit save.
(I'm using a vertical tab field group but i tested without a group and it's the same)

That's wired, if this doesn't happen to you I guess I have to further investigate why it happens to me. I'm gonna try that on a fresh empty D7 site.

1. Browse for and upload a file
2. After the file has uploaded, I see the thumbnail and I Don't see an 'Add a new file' button

I have to save the whole profile to actually see it again.

Oh well, that's going to be fun. I created an empty clean D7 testing site and it works there. So I guess I'll have to go all the way activating modules, themes, etc. untill this problem appears again if I want to know what causes that.

Found it! It's the field translation module: http://drupal.org/node/1130518

@joachim: Thank you very much to answer even on saturday :-) I really appreciate.
I didn't find any web page, blog, pdf nor video with much informations about rfay's Copenhagen session, just the attached document. Having a debugging environment equivalent to your production site is the first thing I did and then I disabled the modules I thought where relevant considering my issue.

I'd like to recommend module filter (http://drupal.org/project/module_filter) wich is so helpfull when you have to manage and disable so many modules!
