From Mathias Froehlich, "I have attached an updated version of the VRML2 loader.

Browse Source 
That change is the result of the '[osgPlugins] VRML plugin - "file" url'
discussion on osg-users.

The attached change avoids rewriting file names into some kind of file urls
and then use the url for opening an fstream. Instead just use the given file
name to open the stream.
Also this change adds some Notify output for the error paths.
