This is with JON hudson build #172

This exception shows up regularly in console log. 
While there is a nice "don't panic" message at the end - can't we just catch the "duplicate entry exception", log a one-liner and not log those stack traces -- as we pretend to know that they are harmless anyway.

The current situation only frightens the users.
