Have you checked whether the service names match? Gmapping names the service "dynamic_map", while the Navigator defaults to "get_map". You can use the Navigator's "map_service" parameter to tell it what service to call for the map.

Edit: Can you read my comments? Something seems broken... It helps to visualize both global map and local costmap in RVIZ to see what is actually happening.

Can you post a sceenshot from RVIZ with the map, costmap and the green/blue movement indicators? However, if your laser reports an obstacle, the Operator will try to avoid it. There is probably little you can do about that from the costmap-side.costmap-side. Maybe you can pre-filter the laser scan?
