I can reproduce this on 21316.  I'm not sure which of these steps is absolutely
necessary, but this is what I do: 

1. clean-cache and run Kepler.
2. Create a trivial workflow.  Opening an example workflow does not trigger the
bug.  This is what I use: 
 a. SDF Director.  Set iterations to 1
 b. Expression actor, set expression to 1
 c. Another Expression actor (Expression2), add an input port called in, set
expression to in
 d. Hook Expression.output to Expression2.in
3. Save the workflow (I put it into kepler\workflows\test.xml)
4. Save Archive (KAR) (I put it into kepler\workflows\test.kar)

At that point, Kepler should abort with an NPE on the console.  I have only
tested this under Windows.
