When I try to load stanchion through the command stanchion console, I get this:

Anyone know what's up? Here's my stanchion.conf:
`nodename =

distributed_cookie = riak

platform_log_dir = /var/log/stanchion

platform_data_dir = /var/db/stanchion

platform_etc_dir = /etc/stanchion

riak_host =
listener =

stanchion_ssl = off

admin.key =

admin.secret =


Seems to be a cuttlefish problem. I'm running on Erlang R16_Basho10

+1 on this issue:

lists:unzip([[ws,ws,ws,ws,ws,ws]], [["listener"],["riak_host"],["nodename"]], ["","", ""])

is not a zipped list and the reason is the 'ws' list.

I did some tests with cuttlefish 2.0.10 and also had the same issue.

As far as I found out the reason are lines containing only 'space'.
So "\n" is not an issue but " \n" is an issue.
