Key import segfault in libgcrypt

[Hanno Böck]

Hello,

On my system if I try to import this key
http://pgp.mit.edu/pks/lookup?op=get&search=0x98EEB6F7D87171CF
with gnupg it segfaults.

Backtrace (see below) indicates that the crash happens somewhere in
libgcrypt, so I'm posting it here.

My libgcrypt version is 1.6.1, gnupg is 2.0.22.

I can reproduce it on another system with libgcrypt 1.5.3. Both are
Gentoo.

Can anyone else reproduce? Any more info needed?

cu, Hanno Böck
