Booleans! Yay! Mesh that has difference modifier applied disappears...

… and I’m left with a very nice little piece of mesh floating there that’s the carved out portion.

Using 2.63a build.

In a nutshell, I’m carving a number into a mesh but when I add the boolean modifier and the difference operation the mesh being carved disappears and only the carved bit of mesh is sitting there.

Any ideas what I might be doing wrong?
