I patched GnuPG to solve these issues. For various reasons
(see http://lists.gnupg.org/gnupg-devel-9903/msg00033.html and
     http://lists.gnupg.org/gnupg-devel-9903/msg00037.html)
this patch won't be integrated into GnuPG.

But I still maintain it for my own usage. I can email to anyone requesting it 
the diff between the current GnuPG and my version (don't try the patch in my 
original message).
