Right.
Today, he explained that the K matrix comes from calibration. So, I
clearly will not be able to fix this in the camera1394 driver.
So, it seems like the bug report should be for rviz and not
camera1394. Everyone is going to have this problem initially when they
buy a new camera.
Rviz should not be complaining about NaN values in that situation, it
just confuses users.
