Comment (by shane):

 The following patch fixes the problem:

 {{{

                      // Construct the name with *
                      const Name superdomain(name.split(i));
                      const string wildcard("*." + superdomain.toText());
 }}}

 I still need to make a unit test that causes the failure.
