Outputs an empty xml file every time

[c2c533c4f237]

I can't get the versions below 2.0 (and I'm using rspec under version 3, so until I upgrade it won't work) to output an xml that isn't 0 bytes. I'm not sure what additional information I can include. I put a few debug statements in the main rb file and the only one I was able to trigger was in the initialize method. Any ideas what's going wrong?
