Can't update term fields

After 3 days trying to figure it out, I know what is the cause.

Steps to reproduce.
1. Create a vocabulary with some terms.
2. Create a field.
3. Add some data to the field you've just created and save the term.
4. Go back and edit the term. Change the data in the field and save.
5. The change will be reflected.
6. Add another field, this time make it a FILE field.
7. Edit the same term field you've edited on 4.
8. You'll notice here there's no file field.
9. Try saving the term after making a change on the term field and then edit the term again.
10. You'll see the change hasn't been reflected.

The problem it's caused when adding file fields to the term. Don't know what happened since this was working.

I've just restored a backup and it's working. I also want to add that I'm using Taxonomy Image, I don't think it's a compatibility problem. Right now, with the old version everything it's working.

Version using:
// $Id: term_fields.module,v 1.7 2009/06/11 06:10:27 archard Exp $
// $Id: term_fields.admin.inc,v 1.4 2009/06/11 06:10:27 archard Exp $

It works. Since I'm the only one who found this problem I'll change the status.

Thanks.
