Thinking Sphinx returns "bad multi-query count 0 (must be in 1..32 range)"

I'm trying to use Sphinx (2.0.1 beta) with Thinking Sphinx 2.0.4 (on Rails 3.0.3). I have one model so far that I'd like to add to my index and the indexing has worked. I can also start searchd through rake and see the process running.

However, when trying a simple search in Rails (like User.search "name"), searchd complains about "bad multi-query count 0 (must be in 1..32 range)"

And here is the backtrace:

Ah, I just answered on the Google Group, but here again, for anyone else who finds this question:

This is a bug in Riddle 1.3.2, which is fixed in edge, but there's no new gem release just yet. Add Riddle to your Gemfile (above your thinking-sphinx reference):

gem 'riddle', :git => 'git://github.com/freelancing-god/riddle.git'
