undefined method when importing from friendfeed #1

Hi,
I'm getting this error when executing ./script/runner Post.fetch_from_friendfeed
I'm using rails 2.1.1 (app didn't start with the latest version). My zementa api key is in the environtment.rb (ZEMENTA_API_KEY)
I tried using both http://friendfeed.com/myuser and http://friendfeed.com?format=atom as the url, to no avail.

/var/lib/gems/1.8/gems/rails-2.1.1/lib/commands/runner.rb:47: undefined method name' for "\n\n":REXML::Text (NoMethodError) from /usr/lib/ruby/1.8/rexml/parent.rb:40:ineach'

Ideas?

Thanks!
