Well, the above snippet calls directory-files later on, which is the
call that barfed. This is one API that invokes directory traversal --
a function that reads and returns all the file names in a directory.
Another example is directory-files-and-attributes. Also, any
file-name completion needs to traverse a directory. If some Lisp form
in the call stack also called one of these functions, you could see
this "no error" error, according to my reading of the code.
