Error 500: No known block type for 0

[Abduladem Eljamel]

Hi allI hope you are all fine.I have a TDB store contains a small data. When I 
query that data directly from JENA, I got results and it works fine. But when I 
use Fuseki server (1.0.2) to query the same data with the same SPARQL code, I 
got this error: 
Error 500: No known block type for 0

The data contains two named graphs and the SPARQL query is:

SELECT * WHERE { GRAPH ?g { ?s ?p ?o}} 

I would be very gratefull if any one tell me what is the cause of this error.

Thans in advance
Abdul
