EVP_PKEY_get1_EC_KEY:expecting a ec key

[Oliver Riesen-Mallmann]

Hi,

since my last update from the Dovecot Prebuilt Binary for Debian I get a
lot of messages like this in mail.log:

dovecot: imap-login: Error: SSL: Stacked error: error:0608308E:digital
envelope routines:EVP_PKEY_get1_EC_KEY:expecting a ec key

Nevertheless Dovecot seems to work normally. Email client doesn't
mention any error.

This was my last update:

My current Dovecot version: 2.2.20.rc1 (0b81127e53da)
on Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u1 x86_64

Is it a bug in Dovecot or in openssl/libssl?
