Mantis#2287. Thank you kindly, Idb for a patch that solves:
The current llGetLinkName returns an empty string if a prim
with the given link number is not found in the link set. In
SL an empty string is only returned if the prim name is actually
blank, a NULL_KEY is returned instead with a couple of exceptions.
