Segmentation fault on inclusion of lazer plugin ..camera sensor work fine.
Segmentation on inclusion of hokuyosensor plugin ..camera sensor work fine. Gazebo starts with a blank screen and nothing in the model. If I remove the hokuyosensor plugin the segmentation fault goes away. Any thoughts on how to fix this or another sensor I can use?
