Core dump when "setup the capture workspace"

[NearXdu]

I saw some the same question in #30

but I didn't get the solution...

I follow the step at the page :
http://wg-perception.github.io/object_recognition_core/quickguide.html#quickguide

roslaunch openni_launch openni.launch
rosrun object_recognition_capture orb_template -o my_textured_plane

and i got this:

Listening for key: s on imshow:save
Registration? 1
Sync? 0
python: /usr/include/boost/smart_ptr/shared_ptr.hpp:646: typename boost::detail::sp_dereference::type boost::shared_ptr::operator*() const [with T = xn::NodeInfo; typename boost::detail::sp_dereference::type = xn::NodeInfo&]: Assertion `px != 0' failed.
Aborted (core dumped)

How could I solve this problem ?

I test it under ubuntu14.04 64 bits、 ros-indigo、Microsoft KinectV1
