ROS opencv crashes

so I followed the guide on jetshacks to install ROS on the TK1:

there is a convenience script that builds cv_bridge and vision_opencv from source to get around the 2.4.8/2.4.13 issue, and the realsense camera works fine, but when I launch stock ros nodes like ros-indigo-ar-sys or ros-indigo-ar-track-alvar they crash with:

[ INFO] [1467751176.060964608]: ArSys node started with marker size of 0.150000 m and board configuration: /home/ubuntu/board.yaml

Program received signal SIGSEGV, Segmentation fault.
0xb6d5e766 in cv::Mat::setTo(cv::_InputArray const&, cv::_InputArray const&)
    () from /usr/lib/
Program received signal SIGSEGV, Segmentation fault.
0xb68f6304 in cv::cvtColor(cv::_InputArray const&, cv::_OutputArray const&, int, int) () from /usr/lib/

it’s looking in the right location for the opencv libraries. I’m not sure where these errors are coming from?
