hi all this may also be important: The TDB is fresh (this is the first SPARQL update) and has been created with tdbloader2 from a modified apache-jena-2.7.3 (jena-tdb-0.9.3.jar was replaced with jena-tdb-0.9.4-20120829.061613-27.jar). I was able to tdbdump the TDB with an unmodified apache-jena-2.7.3. All sorts of SPARQL queries have been tried on this TDB and have not yielded any problems.
