jsone failing on node info parsing

[baransu]

I'm playing with Phoenix 1.3 channels right now and stumbled into this error while trying to get node info about probably simple Phoenix.Channel process.
https://github.com/Baransu/e_game/blob/master/lib/e_game/web/channels/room_channel.ex

You can reproduce it by running project from repo (with new Phoenix 1.3 commands) and trying to inspect this node:

From what I see jsone is failing and causing the crash but I don't know what is failing

Error in process <0.227.0> on node 'erlangpl@127.0.0.1' with exit value:
