PrintTask "onError" is not working as expected

See the attached sample, which loads a simple map with a tiled layer and attempts to run a printTask using a sample Esri server at Web Map Task

printTask.execute(params, printResult, printError);

If you watch in FireBug, this immediately returns an error message:

NetworkError: 503 Service Unavailable... server is at capacity
However, the printError function doesn't seem to fire, and doesn't contain the message about the server being unavailable/at capacity.

EDIT: it does correctly return an error response if I point it to another print server which exists but is switched off.
