Indeed, thanks to report.

The problem is tramp that is not loaded.
If you do as following, things should work as expected:

emacs -Q

In scratch buffer, eval:

(add-to-list 'load-path "path/to/your/anything/files")
(require 'anything-config)
(require 'tramp)
(defun my-file-browser ()
  (let ((fname (anything-c-read-file-name "AnyPrompt: ")))
    (message "FILENAME: %s" name)))
(my-file-browser)

Yes, because anything-find-files load tramp, but
anything-c-read-file-name doesn't.
I will fix it as soon as possible.

What mysterious things?
Can you give examples?
