[ignazio1977]

Bug in owlmanager and in the reasoner used: the reasoner is guaranteed not null at that point, but there is no guarantee that the reasoner name is not null. However the reasoner should be nice about it.

Can be fixed in OWLUtils.

Will be fixed with the next release of ontology-browser
