ethz_icp_mapper indigo process crashes at start

edit

Hi all, I have a 64-bit 14.04 ubuntu machine with Indigo and I'm trying to run the ethzasl_icp_mapper.

I installed libnabo and libpointmatcher through apt-get apt-get install ros-indigo-libnabo ros-indigo-libpointmatcher

and cloned the mapper from the github inside my workspace/src directory after checking out the ros-indigo-devel branch

When I run the mapper node with this:

<launch>
        <node name="mapper" type="dynamic_mapper" pkg="ethzasl_icp_mapper" output="screen" >
                <remap from="cloud_in" to="/velodyne_points" />
                <param name="publishMapTf" value="true"/>
                <param name="localizing" value="true" />
                <param name="mapping" value="true" />
                <param name="subscribe_scan" value="false" />
                <param name="subscribe_cloud" value="true"/>
                <param name="odom_frame" value="velodyne" />
                <param name="sensorFrame" value="velodyne" />
        </node>
</launch>

I get this:
