That looks like the _floor image to me. Are you missing a _floor image, or do you have a blank _floor image?
In 1.5.13, a missing _floor image would result in a little black box for some people, while a blank _floor image would get rid of the box. I don't know how 1.6.x reacts to either of those situations, but it looks like a yellow caution sign in your screenshot.
I haven't examined the resources of 1.6.3 yet, but I have tested the last ship I've made which included a blank image for something, and that blank image isn't working anymore, instead giving me a red warning sign. I don't know yet if it is because of a different file location, or the new FTL version doesn't like the blank image.
