Dear Maintainer,

when trying to send my key to the key servers, GnuPG 2.1 fails:

    $ LANG=C gpg2 --send-keys a4ff2279
    gpg: sending key A4FF2279 to hkp server pool.sks-keyservers.net
    gpg: keyserver send failed: Too much data for IPC layer
    gpg: keyserver send failed: Too much data for IPC layer

`gpg --send-keys a4ff2279` works fine; exporting the public key data and reimporting to a completely new and empty `--homedir` did not help, so the problem should be reproducible with the attached public export (the data available on keyservers should be equal or a superset).

This is not a stopping bug as using GnuPG 1 works as workaround, but rather annoying.

Regards,
Jens
