I am not sure to understand how this is a bug. Because of the fix you
proposed, I assumed you meant that empty fragments were not allowed in
RDF, but I couldn't find any specification against that.

Actually, [1] suggests that this is a valid approach.

And it looks like Facebook agrees:

[[
$ GET -H 'Accept: text/turtle' http://graph.facebook.com/627001044
...
</627001044#>
	user:id "627001044" ;
	user:first_name "Alexandre" ;
	user:gender "male" ;
	user:last_name "Bertails" ;
	user:locale "fr_FR" ;
	user:name "Alexandre Bertails" ;
	user:username "bertails" .
]]

And libraries like Sesame or Jena seem ok too.

As for using Tim's WebID directly, we (the editors) thought about it
and didn't like the idea, because 1. we simply do not own that
document (obviously), and 2. the example data does not exist there.
