gpg-agent "unknown value for WHAT"

[David Savage]

Hi there,

I'm attempting to generate a 4096bit RSA key using gnupg 2.0.12 and
gpg-agent 2.0.11 but I'm getting an error message prior to entering
the passphrase:

"gpg: problem with the agent: Not supported"

Having done a little digging I decided to enable --debug-all to see if
this would shed any light on the problem - unfortunately the error
message means very little on first inspection - hence this mail.

"gpg-agent[66760.6] DBG: -> ERR 67109144 parameter conflict - unknown
value for WHAT"

I've included the full session output below with certain fields XXXXX'd out...

_Environment_info_
Mac OS X 10.5.8
gnupg2 installed via darwin ports

_Non_standard_entries_in_"~/.gnupg/gpg.conf"_
personal-digest-preferences SHA512
cert-digest-algo SHA512
default-preference-list SHA512 SHA384 SHA256 SHA224 AES256 AES192 AES
CAST5 ZLIB BZIP2 ZIP Uncompressed

Any help or suggestions of where to look further appreciated.

Regards,

Dave
