  Thanks for the testcase.  I see the problem and have a patch coming up.  
However it needs some thorough testing and I may back it out again.  The 
patch tells Kst to keep vectors loaded from the commandline around even if 
they're not found in the file because they might show up later.  I think this 
is OK behavior, but I want to be sure that it doesn't cause any problems with 
traditional usage.
