I took a quick look at this. Depending on your point of view, it's
a bug in nlist(3) and/or in the relevant symbols in the kernel. The
symbols come out with an object type of "none", which nlist() then
decides to interpret as undefined. I think it's best to fix it in
nlist(). I know how to fix it, and will try to get to it before the
week is out.
