Cool, but you should patch the .ccg and .hg files instead.

Yes.  Glib::ListHandle objects are used to defer the actual type
conversion to the point where the contents are accessed, and the
resulting container type is known.  So using std::list<> is wrong here,
you need to wrap the GList directly.

Unfortunately this is one of those situations where a special TypeTraits
class for GnomeVFSURI is required in order to be able to use the
Glib::*Handle classes.  IIRC pangomm contains quite a lot of these
custom traits structs, maybe you could have a look there for
inspiration.
