image_transport rosbag issue

$

Has anyone else seen problems recording rosbags for all topics of a node using image_transport? > ERROR > [/tmp/buildd/ros-indigo-compressed-depth-image-transport-1.9.2-0trusty-20150729-0539/src/compressed_depth_publisher.cpp:223(CompressedDepthPublisher::publish) >> ... >> Compressed Depth Image Transport -Compression requires single-channel 32bit-floating point or 16bit raw depth images (input format is: bgr8). I see this with [pointgrey_camera_driver (tag 0.12.1)](https://github.com/ros-drivers/pointgrey_camera_driver.git) when doing a `rosbag record -a`. I've noticed some [issues](https://github.com/ros-drivers/axis_camera/issues/32) posted for other packages using image_transport so I thought I'd post a general question in the event there is some broader issue. UPDATE: Running `rosbag record -a -x "(.*)/compressed(.*)"` solves the issue of the errors by not recording the "compressed" topics but doesn't explain why they occur in the first place.
