Try disabling the inconsistent attachment state check to see if this actually has an impact.

The code in question is over three years old and just be catching an inconsistency rather than being wholly necessary.
This commit still carries out the check and prints all the previous log warnings but a 'failure' no longer prevents avatar region crossing or teleport, and it doesn't give the client the error message.
This will have some kind of impact on http://opensimulator.org/mantis/view.php?id=5672
