I think there's a short issue with the setup. This part:

config.app_host = {
'development' => 'http://...',
'staging' => 'https://...',
'qapodio' => 'https://...'
}[PODIO_ENV]

Cannot start with http / https. It is only domain name

Hm. Never mind the above :)

Figured out the reason for my confusion. PhantomJS was actually failing due to the recommended GA register FB social event call:

FB.Event.subscribe('edge.create', function(targetUrl) { [...]

This little beauty caused my site to fail with Poltergeist, while it worked when I tried for instance www.dr.dk :P

Removed the FB.Event calls, and everything worked as expected :)
