mono camera calibration for a camera mounted on the robot in gazebo

i am trying to calibrate camera mounted on the robot simulated using gazebo, in order to get extrinsic parameters. i had the calibration window but without any action " rosrun cameracalibration cameracalibrator.py --size 8x6 --square 0.05 image:=/camera/robot/imageraw camera:=/camera/robot --no-service-check" . and i got sometimes this error : " (display:5647): GLib-GObject-CRITICAL **: 20:29:58.618: gobjectunref: assertion 'GISOBJECT (object)' failed"
