Segfault using ruby 2

Copied from Q&A site:

http://www.couchbase.com/communities/q-and-a/segfault-using-ruby2

I couldn't find anyone else having this issue, but I'm having trouble getting started with Couchbase using Ruby2. I'm getting a segmentation fault trying to access a document in the beer-sample bucket.

I'm using:
Ruby 2.0.0-p247 (using irb)
libcouchbase 2.1.1 (from homebrew)
couchbase gem 1.3.2

The error is:
2.0.0-p247 :006 > beer = client.get("aass_brewery-juleol")
(irb):6: [BUG] Segmentation fault
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.4.0]
