Unknown key: r (ArgumentError) thrown on rhc client command ssh connection attempt

Issue

I'm getting the following error when running "rhc setup" or "rhc ssh {appName}": "An SSH connection could not be established to home-paranormal.rhcloud.com. Your SSH configuration may not be correct, or the application may not be responding. unknown key: r (ArgumentError)"

Resolution

This was fixed in a recent release of Openshift Online, see here for more information.
