Calvin,
This bug took some time to find, but I got it. XPath was probably the
best way to expose it, since it had to do with random access to nodes
(really freeing them, but what's the difference). It would have had
an impact somewhere else for sure.
It is all committed and an update should yield #187. Give it a try
(one more time).
Hopeful you will report all clear.
