Not an amanda bug, you broke an amanda usage amanda been using for a decade 
or more.

Somewhere in this lists archives, say a month or more back up the log, and 
the thread even includes a test case code snippet to demo the problem, and 
which I thought was going to be added to your "make test: suite.  I'm not 
sure which of the amanda contributors (I am not one, I play the canary in 
the coal mine part in this play) posted the test case code, my memory says 
it may not have been Jean-Louis M.  I would go find it in my email corpus 
here, but due to speed and disk usage constraints, I have kmail expiring 
this folder at 30 days.  It is nearly 21Gb as it is. Next time I install, 
/home is going to get 100Gb to play in.

Perhaps Jean-Louis is copying the list, and can refresh that thread?
