Tried to subscribe to a topic with the same name but different md5sum
I am trying to launch lsd_slam, as,
rosrun lsd_slam_core live_slam /image:=/ardrone/front/image_raw /camera_info:=/ardrone/front/image_raw
and then I get the error,
rosrun lsd_slam_core live_slam /image:=/ardrone/front/image_raw /camera_info:=/ardrone/front/image_raw
terminate called after throwing an instance of 'ros::ConflictingSubscriptionException'
what(): Tried to subscribe to a topic with the same name but different md5sum as a topic that was already subscribed [sensor_msgs/CameraInfo/c9a58c1b0b154e0e6da7578cb991d214 vs. sensor_msgs/Image/060021388200f6f0f447d0fcd9c64743]

I had been running lsd_slam
successfully for some time. I know not what changed in the setup.
