Hello:

I just committed revision 64907, migrating d-i's manual Spanish translation
to gettext.

Sorry if I raised an eyebrow here... I tried to reproduce but couldn't.
I'm on a new install, maybe the old one was missing something.

Only warning with ./scripts/create_xml with at least es and pt:

- creating boot-installer.xml
found empty tag para
found empty tag para
- creating install-methods.xml

but it builds just fine.
