You should be able to use any Gmsh *.msh file to load it up via the
GmshIO reader. However you cannot read a *.geo file because this is
only a preprocessing geometry file and not a mesh file. I've attached
a simple mesh file (8 cubes) which should load up with any libmesh
example. Note that I changed the version number to 2.1 here.

This is probably because you are not creating your Mesh object
correctly. The Mesh constructor takes dimension as an argument and by
default, it is 1. Try creating
int dim = 3;
Mesh mesh(dim);
mesh.read("src.msh");
If you have problems still, let us know.
