I tried this using ruby 2.0.0p247 and ruby 1.9.3p448.

The same thing is happening with riemann-redis, too. Did not check more tools.

This is probably due to a change in Beefcake; seems to have introduced a regression. We may just be able to drop our use of frozen strings, though.

Fixed in 0.1.5.
