void-generator fails on DEFAULT graph with graphDB

[mpagni12]

In GraphDB, I have created two repositories and uploaded the same RDF data in them (a RDFS schema). The only difference is that the data were uploaded in the DEFAULT graph in one case, and in a named graph in the other case. The void generator (run with -r -i -s options) returns the expected result for the named-graph repository. But, it returns only the service description for the DEFAULT graph repository, i.e. void partitions are completely missing:
