Could not set name to NAME, error code 4294967295. Looks to me like this bug has been around forever. It is still not fixed?
That error is an ugly way of telling you that the name you want to change to is unavailable. Try another name or a different spelling of the one you want, and with luck, it will go through. (And yeah, they said they were going to make the error message a bit more clear a while back, but we are still stuck with our buddy "4294967295" for now.)
