The fix for this bug is in ros_comm 1.6.6, just released.
To summarize the bug: in ros_comm 1.6.5 (and only in 1.6.5), rosbag
improperly records data when: multiple topics of the same type are
published by the same roscpp-based node. In this situation, data from
multiple topics are stored in the bag as if received via just one of
the topics. A common example of this situation is recording both rgb
and depth data from openni.
