Please see
http://www.gnupg.org/buglist.html
for a list of know bugs in GnuPG. We don't distribute this list anymore
with the package because a more current one with notes in which version
the bug is fixed can be found online.
For security related bugs, please contact which
directs mails only to the core developers. If you need to encrypt the
report you should use the public keys of the maintainer and of 2 or 3
other active developers (consult the ChangeLog and AUTHORS).
