I am running the turtlebot kinect arm calibration tutorial on Fuerte and Ubuntu 12.04 Precise. I step through the stages of the calibration process, using an off board kinect and the calibrate_old_kinect launch file. However, after setting all 4 points, I get the following error, and the calibration stops responding:

calibrate_kinect_checkerboard: /usr/include/eigen3/Eigen/src/Core/ProductBase.h:108: Eigen::ProductBase<Derived, Lhs, Rhs>::ProductBase(const Lhs&, const Rhs&) [with Derived = Eigen::GeneralProduct<Eigen::Matrix<float, -0x00000000000000001, -0x00000000000000001>, Eigen::Transpose<const Eigen::Matrix<float, -0x00000000000000001, -0x00000000000000001> >, 5>, Lhs = Eigen::Matrix<float, -0x00000000000000001, -0x00000000000000001>, Rhs = Eigen::Transpose<const Eigen::Matrix<float, -0x00000000000000001, -0x00000000000000001> >]: Assertion `lhs.cols() == rhs.rows() && "invalid matrix product" && "if you wanted a coeff-wise or a dot product use the respective explicit functions"' failed.

Has anyone else encountered this error and have a suggestion as to how to fix it? Thanks!
