Ouch. It seems there are two issues here. One bug which didn't report a
parsing error back to the caller (was fixed) and the fact that openssl
uses an old format for storing ECC private keys.

GnuTLS uses the format from RFC 5915 for ECC keys. OpenSSL seems to be
able to read this format, but I couldn't find an option to generate keys
using this format.
