Hello kuriyama@FreeBSD.org,

There seems to be a bug in GnuPG 2.1.x dirmngr which let it crash; the
attached diff at least solves the crash, even if there are other errors
while searching for pub keys :-(

Subject: keysearch fails


Hello,

I can not manage to get a keysearch via dirmngr to work; when I use:

$ gpg2 --keyserver pool.sks-keyservers.net --debug 1024 --search xxxx@FreeBSD.org
gpg: reading options from '/home/guru/.gnupg/gpg.conf'
gpg: enabled debug flags: ipc
gpg: DBG: chan_3 <- # Home: /home/guru/.gnupg
gpg: DBG: chan_3 <- # Config: /home/guru/.gnupg/dirmngr.conf
gpg: DBG: chan_3 <- OK Dirmngr 2.1.6 at your service
gpg: DBG: connection to the dirmngr established
gpg: DBG: chan_3 -> KEYSERVER --clear hkp://pool.sks-keyservers.net
gpg: DBG: chan_3 <- OK
gpg: DBG: chan_3 -> KS_SEARCH -- xxxx@FreeBSD.org
gpg: DBG: chan_3 <- [eof]
gpg: error searching keyserver: End of file
gpg: bรบsqueda del servidor de claves fallida: End of file
gpg: DBG: chan_3 -> BYE
gpg: secmem usage: 0/32768 bytes in 0 blocks

In /var/log/message I see:

Dec 23 09:15:09 c720-r285885-amd64 kernel: pid 2809 (dirmngr), uid 1001: exited on \
signal 6

which perhaps is normal (soemhow the spawned proc must be killed); but a
TCPDUMP only shows a lot of PTR requests, see below. No real traffic is
to be seen to no server.

What I do miss here?
