What you want to do is look around at these values.  Why is the object
being probed invalid (0x1)?  Is it simply not initialized?  When you
do a "call sel_get_name (op)" in that top frame, do you get
respondsTo:, as expected?  Relate the line numbers to the Swarm source
code and deconstruct the situation...
