"failed to parse Merlin error message"

[brabalan]

I've just set up flycheck-ocaml as described in the README, and I have an error with my first try.

I open an empty ml file and write let x =

and after a few seconds I have this in a *Warnings* buffer:

Error (flycheck-ocaml): Failed to parse Merlin error message "Syntax error inside `let', expecting `:' or `=' function body" from ((assoc) (type . "parser") (start (assoc) (line . 2) (col . 0)) (end (assoc) (line . 2) (col . 0)) (valid . true) (message . "Syntax error inside `let', expecting `:' or `=' function body"))

I'm using merlin from git, and flycheck from Melpa.
