This says that receiveUtteranceFrom is sending a message (0x804d580)
to receiver 0x815ec10.  You can look at the class of the target by using
"print ((Class *) receiver)->name" and you can look at the selector
name by using "call sel_get_name (op)".  The latter will probably not
work unless you have a version of Swarm you built your self without 
inlining.

Typically this sort of thing happens when you send a message to an object
that has been dropped, or you have an uninitialized target variable, or
the message you are sending doesn't exist in the target (e.g. a typo).
