To improve performance POV-Ray uses object bounding to reduce the number of 
objects it needs to check when tracing rays. Explode.inc doesn't seem to 
manually specify any bounding box, so I assume that POV-Ray has tried to 
generate a bounding box automatically and it ended up with a box where one 
or more dimensions was zero, so it's not bothered using it and has continued 
without a bounding box for that CSG object.

This shouldn't impact the resulting image, but may result in the rendering 
speed being less optimised.
