The unstable build of robot_model on maverick is passing (http://build.willowgarage.com/view/devel_unstable/job/devel_unstable_robot_model_maverick_amd64/), but it's using robot_model/branches/robot_model-1.4, and there are significant differences between that branch and trunk. We don't currently have an automated build of robot_model/trunk (it should appear after the Diamondback release). That's a long-winded way of saying that something problematic seems to snuck in on robot_model/trunk. brian.
