[vtk-developers] seg faults with potential test

I have a test to submit for vtkImageTracerWidget but am
having problems with seg faults.  The code for the test
is cxx adaptation of /Examples/GUI/Tcl/ImageTracerWidget.tcl 
and runs without err when set up as a simple stand alone
exe. When framed within the typical test harness for a
widget (e.g. Hybrid/Tests/Cxx/) using a vtkInteractorEventRecorder
to play back events, the recorded events for the spline widget cause
seg fualts.  The problem seems to be with setting a callback for
an EndInteractionEvent with the spline widget in the second renderer.  
I can set the default renderer to be renderer2 and proceed without err
but only without setting the spline's callback (it doesn't matter
if the Execute body of the callback does absolutely nothing...)
Any thoughts?
