[OpenSCAD] adding a difference causes 2-manifold error?

I'm modifying a file from ThingVerse, and have run into an odd problem.
I added a couple more shapes to a long difference() (chopping a couple edges sloped instead of vertical)

and now I get the "WARNING: Object may not be a valid 2-manifold and may need repair!" message.

File is at http://casadelgato.com/work/v2.scad
(yes, it's messy...)
