I succeeded to repro:

$ gem install hallon
$ ruby -rhallon -e 'def (Hallon::Session).instance(*args, &block); @instance ||= new(*args, &block); end; Hallon::Session.instance("invalid")'

snip

This trace strongly suggests that this issue is a fault of libspotify.
The source of libspotify looks unavailable, so we can no longer investigate this issue.
Could you please contact Spotify?
If they say this is a ruby fault, please ask them to disclose their source code.
