True Dominik, it's not solved, I should rather say I can put it on ice 
for a while while I attend to another issue more pressing. I will get 
back to it and I'll let you all know what I found.  It is probably 
exactly as yourself and Bart suspect.  I will catch it.

Roman:

I just want to point out that in general you need to quote the array
expansion here or you'll get surprises if the array has empty keys
and/or values. Consider this:

     typeset -A main=(
       foo '1'
       bar '2'
       baz ''
       qux ''
     )

     printf  '%-4s = %s\n' ${(kv)main}

And the output:

     foo  = 1
     baz  = bar
     2    = qux

... this is exactly the sort of thing I was talking to Lawrence about -- 
not really a hard error, just some printout issue.  I'll pursue that.  I 
(think I) understand that AAs are very fragile creatures and as you 
demonstrate, easily confused.  I'll bag it.
