Activating git-gutter-plus produces a tramp error during initilisation

[dahanbn]

I have only a simple git-gutter-plus configuration:

(use-package git-gutter+
    :if (executable-find "git")
    :init
    (global-git-gutter+-mode))

It worked fine. Since a week or so I will get on each start the following error message:

Debugger entered--Lisp error: (error "Wrong ‘tramp-syntax’ defined")
  signal(error ("Wrong ‘tramp-syntax’ defined"))
  error("Wrong `tramp-syntax' defined")

If you look at the backtrace.txt (debug output), you will see the error message is produced in context of git-gutter+. If I disable git-gutter+ than I won't get any startup error.

Regarding tramp I don't use or configure it anywhere in my config file. I use git-gutter+ 20151204.923 on Emacs GNU Emacs 25.3.1 (x86_64-w64-mingw32).
