I've had a chance to experiment a little more, and it's clear that what is crashing the kadmind is a second or subsequent kpasswd attempt for a given principal a short time after a (successful) first change.
It's as though there's some time window after a kpasswd invocation on a principal during which additional kpasswd invocations will crash the server's admin daemon. It seems to be independent of the particular principal or client machine. -- A. -- Dr. Andrew C. E.
