Ruby Readline crashes console on up arrow

When I press the up or left arrow in the Rails console I get this bug:

irb(main):001:0> /Users/me/.rvm/gems/ruby-2.0.0-p247/gems/rb-readline-0.4.2/lib/rbreadline.rb:4269:in `block in _rl_dispatch_subseq': invalid byte sequence in UTF-8 (ArgumentError)

I use rvm to manage my ruby installations. I'm using 

=> ruby-2.0.0-p247 [ x86_64 ]

I use bundle to manage my gems, and I have rb-readline (0.4.2) (which people recommend as the least buggy version).

What do I need to do to eliminate this hideous bug once and for all?

I'm on Mac OS X 10.8.3. My rvm requirements are already up to date:

$ rvm requirements
Installing requirements for osx, might require sudo password.
Certificates in '/usr/local/etc/openssl/cert.pem' already are up to date.
Requirements installation successful.

uninstall the rb-readline gem - RVM should get readline headers for compiling ruby which in turn should make ruby readline compiled and all should work
