You probably need svn commit r1953

 	- Fix for parent-child disagreement code which could have trouble
 	  when (a) ipv6 was disabled and (b) the TTL for parent and child
 	  were different.  There were two bugs, the parent-side information
 	  is fixed to no longer block lookup of child side information and
 	  the iterator is fixed to no longer attempt to get ipv6 when it is
 	  not enabled and then give up in failure.
