Try

  (load #f)

and you'll get the same error.

`load' requires string as an argument.  AFAICS in the Guile
reference manual, probably the function is supposed to work in
REPL only (while it works without it).

If `%search-load-path' is not able to find the file you want to
load, it returns #f.  You can check your `%load-path' if the
directory with that file is listed in that variable.  If not, use
`add-to-load-path "the-dir-your-file-resides-in"' to make it work,
or use the absolute path of the file.
