I have the same problem under fuerte/12.04. I also get the boost assert (also mentioned in Before this assert, I get one threading-related python exception per process:

Exception AttributeError: AttributeError("'_DummyThread' object has no attribute '_Thread__block'",) in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored

The problem seems to be a conflict with the Linux driver. Removing it with

sudo modprobe -r gspca_kinect


sudo modprobe -r gspca_main

solves the problem.

After some more in-depth experiments, it seems that openni_camera is crashing often here on fuerte/12.04
