From Rein Kadijk, "While displaying a certain scene, OsgEdit crashed in ProxyNode::traverse() in file OSG_OP_OT-1.2\OpenSceneGraph\src\osg\proxynode.cpp.

It turned out that nv.getDatabaseRequestHandler() returned NULL; using this pointer to call one of DatabaseRequestHandler's methods is of course illegal.
I patched it by adding: if (nv.getDatabaseRequestHandler())"

From Robert Osfield, reordered the addition of the nv.getDatabaseRequestHandler() check to allow the
default traverse() to be called when no database handling is attached to the visitor.
