Good point. After removing the empty <archive> tag, and after removing
any comments[1] in the .xml file, the error message changes. And that was
most likely the reason I blamed it to the license stuff:

The effects are that
1. elbe-build-*/licence.txt has size zero,
2. sda.img.gz is not produced or not downloaded ... let me check.
    It seems sda.img.gz is not even produced.

So I disable the extraction of the licenses, just to make sure ...  
building ...
1. licence.txt is not produced/downloaded any more, OK.
2. sda.img.gz is produced and downloaded, OK!


Thank you for your patience.
Cheers,
Erich


[1] is there a reason that lxml is called with  
"remove_comments=False"? (elbepack/treeutils.py class etree(ebase))
