The text 6576f60d8546, as Debian 7 (Wheezy) shipped it.
The SoQtExaminerViewer class is a 3D-model examination viewer. This class is the viewer considered to be the most 'general purpose' viewer, and it is often used in rapid prototyping to examine simple models aswell as complete scenes (although for the latter, you might be better off with one of the other viewer classes).
