You're right - this key has an ECC subkey for signing. I've imported this key into another pc using Deb8, gnupg 2.1.3, Icedove and enigmail 1.8.2 and it doesn't cause any problem on that setup. I tried to re-import it into the original desktop system to see if the problem recurred. (I should have done that before writing the last mail, to confirm fault). With the original desktop : gpg 1.4.16 and gpg2 2.0.22, Thunderbird with enigmail 1.8.2 : - enigmail filed to import the key - gpg2 failed with the message gpg2 --recv-keys 0x6e767393 gpg: requesting key 0x6E767393 from hkp server pool.sks-keyservers.net Version: SKS 1.1.5 gpg: armour header: Comment: Hostname: sks.alpha-labs.net gpg: armour header: gpg: can't handle public key algorithm 19 gpg: pub 4096R/0x2A234ABC6E767393 2013-10-08 Jacky Alciné <y...@jacky.wtf> gpg: key 0x2A234ABC6E767393: removed multiple subkey binding gpg: can't handle public key algorithm 22 gpg: can't handle public key algorithm 18 gpg: Ohhhh jeeee: can't encode a 512 bit MD into a 608 bits frame Aborted (core dumped) - gpg imported it ok - gpg -k runs to complete listing showing the problem key as the last one in the listing (which it is) -gpg2 -k runs listing but stops just before the problem key which it does not list and gives this same message : gpg: Ohhhh jeeee: can't encode a 512 bit MD into a 608 bits frame Aborted (core dumped) - enigmail will not list this key I have other keys in my public keyring which also have ECC subkeys and these do not cause any difficulty either with enigmail or gpg2.0.22 So far it is only key 0x6e767393 which causes the problem.
