Camera_calibration is frozen!

Hello, i've this launch:

<launch> <node pkg="gencam_cu" type="gencam_cu" name="driver_camara"> </node>

<node pkg="image_view" type="image_view" name="image_view"> <remap from="image" to="image_raw"/> </node>

<node pkg="camera_calibration" type="cameracalibrator.py" name="camera_calibration" args="--size 8x6 --square 0.108"> <remap from="image" to="image_raw"/> </node>

</launch>

I run this launch while: roslaunch my_package_test prueba_gencam_cu_video1.launch

I calibrate the camera but when i click on Calibrate, the application is frozen and i don't know why :S.

Any idea to solve this problem?

Thank you!
