 Hello there!

 Along this message is the patch file which in fact could be understood as
 a fix.

 The "xmlnode_free" method implementation don't consider that the
 parent->lastchild member could pointer to the node being freed.

 When this happens, new nodes added throught "xmlnode_insert_child" are not
 accessed correctly.
 Please let me know whether is everything all right, or not.

 Thank's and best regards!
 Mauro.
