'public' dir missing when exporting 'XML3D only'

[fnunnari]

If I try to export a scene with template 'XML3D only' I get the following error message on the console:

FileNotFoundError: [Errno 2] No such file or directory: '/Users/fanu01/Library/Application Support/Blender/2.75/scripts/addons/io_scene_xml3d/templates/xml3d/public'

Indeed, in my .../Application Support/.../templates/xml3d/ folder, the 'public' folder is missing.
(Maybe dropped by GitHub because empty?)

Environment: MaxOSX 10.9, Blender 2.75a and 2.70, exporter 0.4.0.
