Not able to subscribe to image_raw message

[shivamsardana]

OS : VMWare Ubuntu ROS Kinetic

I am using bebop_autonomy package with RotorS package (https://github.com/ethz-asl/rotors_simulator). I am able to subscribe to other rostopics but I am not able to subscribe camera topics. Evey time, let's say I try to view Bebop images in rviz, Gazebo get crashed. If I run rostopic info bebop2/camera_base/image_raw, it says nothing is published.

Can anybody here help me resolve this?
