Segfault when id'ing user

[maleadt]

When trying to id myself, I'm getting a segfault using the latest keybase client:

• keybase 0.8.3-1
• nodejs 0.12.5-1
• distro: Arch Linux

I'm thinking it has something to do with the strange temporary situation I'm currently in concerning my second DNS proof (I already have a file hosted, but also wanted to add a TXT record for _keybase.maleadt.net): the Keybase site hasn't picked-up the TXT record up yet, but it is definitely there and the client should be able to verify it:

$ host -t txt _keybase.maleadt.net
_keybase.maleadt.net descriptive text blabla

However, the keybase homepage hasn't picked this up yet.

NINJA EDIT: I just had a look at what the API (more specifically, lookup.json?usernames=maleadt returns, and it doesn't contain a reference to my secondary DNS proof at _keybase.maleadt.net, so my speculation above likely isn't correct.

Anyhow, here is the crash:

The segfault seems to happen just before it would verify the DNS proof.

A GDB backtrace (relatively useless because of the lack of debugging symbols):

I just noticed the debug flag, and this is the end of it (I listed both DNS proofs):

debug: ++++++ maleadt: checking remote generic_web_site proof
debug: |||||| remote service desc is {"hostname":"blog.maleadt.net","protocol":"http:"}
debug: +++++++ Calling into scraper -> {"hostname":"blog.maleadt.net","protocol":"http:"}@generic_web_site -> http://blog.maleadt.net/keybase.txt

Seems like node still had a bug in their DNS resolver. I filed a bug
report a while back.

Seems like I missed that, and this bug is duplicate to keybase/keybase-issues#1413 and keybase/keybase-issues#1607. I'll close this issue, while waiting for nodejs/node-v0.x-archive#9300 to land.
