     Since I've done nothing to modify the code, I have to assume this is a bug.
     
On the face of it, it sounds like it.   

However you haven't said

1) Which version of pspp you are using (perhaps it is a bug which has
already been fixed).

2) Exactly what did you do (what sequence of menu actions did you
perform) to provoke this behaviour.

If you can provide this information, the hopefully we can investigate
and if necessary correct the problem.
