Apologies for missing this message last fall.  Independently figured out and fixed the same issue tonight.

Modified x3d.py as follows,

    if self.head.hasChild():

got changed to

    if self.head and  if self.head.hasChild():

This fix will be in the next release.

No longer sure what that one is... if still a problem, please send example.  As always, thanks.
