Right now, the test doesn't run properly at all, so I can't reproduce the error:

Is this what you see as well? If not, could you find out what's wrong with the test?

I've fixed the original issue in SVN 20409 (2nd retry-send-key task added, which overrode the original task and then was never canceled). However, the DHT test failure remains open (but thats another issue which I'll file separately).
