Hi Samuel,

It's probably the same thing as the other time. The data has the label 
as a typed literal with datatype xsd:string -- in SPARQL this is 
represented lexically as:

"bifinhos com cogumelos"^^xsd:string

If you change your query to that, I expect you'd get results with both 
protege and jena. What's happening apparently here is that Jena is 
adhering to the precise semantics of SPARQL while protege is being a bit 
lax.
