[vtkusers] breaking after vtkErrorMacro

From looking at the code in vtkSetGet.h for vtkErrorMacro, it seems
that if something is observing the "ErrorEvent", then that event is
invoked. Perhaps you could add an observer to the filter that has this
problem -- specifically listening for the "ErrorEvent". Then you could
exit gracefully in your event handler.
