You're making the assumption that the returned node always is a Geode.
This may not always be the case, e.g. because the loader decided to place a
MatrixTransform or a Group at the root of the loaded graph. In these cases the
dynamic_cast will return a NULL pointer which would explain the crash.
Just use a osg::Node* and remove the dynamic_cast and you should be fine.
