Dear Werner,

as you wished here are the results of the german jury ...uh... the results
of my tests of course :-))))

Start gpg with the following parameters:

  gpg --batch --yes --status-fd 1 --export -a -o sav/asckey_jt

and capture stdout (same as status-fd in this case in fact of
the --status-fd 1 parameter) and stderr from gpg, assuming, that there is NO
public key with the UID in the pubring (an so the expected
error occurs) will produce the following output on the different handles:

on stdout (or status-fd):
There is NO, Nothing, Nada, nix, garnix! Not even one line!

on stderr:
There is the following output:

  gpg: WARNING: nothing exported

The returncode from gpg in this case seems to be 0 (should'nt it be at least

I think there should be at least also a [GNUPG: ] NO_PUBKEY Msg. on the

Thanks for your advice and good work. If you need more information about
this please contact me again.

CU all
