The point is that all.files=TRUE implies returning also "." and
".."!
Hence the recursion uses to be infinite (from "." to "." to
"." ......).

If recursiv = TRUE, the function should never look into "." and
"..",
except of the first step of the recursion.

I'll fix this in r-patched.  It may be a few days before I'm able to
commit the change, though.
