Internal error returned from within gnutls_certificate_set_openpgp_key()

[Joke de Buhr]

hi,

i'm using GnuTLS version 3.1.1.

there seems to be a problem within gnutls_certificate_set_openpgp_key().

gnutls_certificate_set_openpgp_key() uses gnutls_privkey_import_openpgp() (flag 
GNUTLS_PRIVKEY_IMPORT_COPY) to obtain a copy of the passed private key.
copying is done calling _gnutls_openpgp_privkey_cpy() with in turn calls 
gnutls_openpgp_privkey_export() and gnutls_openpgp_privkey_import().

during this copying procedure the key somehow gets messed up and 
gnutls_openpgp_privkey_import() returns GNUTLS_E_INTERNAL_ERROR.

importing the private key with gnutls_openpgp_privkey_import() in the first 
place to pass the parameter to gnutls_certificate_set_openpgp_key() worked 
without problem. the pgp-key contains a master-key with flags SCE and a single 
subkey with flags SEA. using a pgp-key with just a master-key seems to work by 
the way.

if needed i'm can provide a test program and the gpg-key.


regards
Joke
