Segfault when in case server name resolved to several addresses, where first of them rejects couchbase connection

I get a lot of segfaults using the client when trying to connect to _external_ couchbase servers (i.e. when there is no couchbase server on localhost).

I've tested this on a couple different machines, with both ruby REE and 1.9.3 - same results every time.

To reproduce:
1) setup couchbase server / cluster on machine-1
2) setup ruby development environment on machine-2
-- I'm using rvm
-- I've install the couchbase library
3) run simple ruby program to test connections:
#simple_test.rb
require 'couchbase'
Couchbase.connection_options = {:bucket => 'rubytest', :node_list => ['123.45.67.89:8091'], :password => 'password'}
Couchbase.connect
4) watch it segfault when you run it

Essentially, it seems that setting the 'connection_optoins' has no effect on creating new buckets, they keep trying to connect to the built-in default of 'localhost'

This is especially problematic because of what it means trying to use couchbase in production: If I work around this by passing connection options to a new bucket, I will eventually run into this same segfault issue whenever the cluster I am connecting to is rebalancing - I've gotten quite a few segfaults when adding / removing nodes and then rebalancing.
