I open the file with Emacs server mode enabled, and open it with emacsclient.
I got this error backtrack sometimes when I open a bash script file, and do some modifcations, and try to save this file. Then I got this error.

And I have not meet this error in other formats. and not in a opened new file.

My Emacs version: "GNU Emacs 25.0.50.2 (x86_64-unknown-linux-gnu, GTK+ Version 3.14.4)\n of 2014-11-03 on dark"

Please try to load the uncompiled source by adding to following to your config:
(load "path/to/git-gutter+.el")

That should give a more detailed backtrace. Right now, I can't see which function call is failing.

[stardiviner]

After load that file, I got this output from shell,
*ERROR*: Wrong number of arguments: nil, 0
And have a shell command alias
alias e=emacsclient -c

[nonsequitur]

So you added (load "path/to/git-gutter+.el") to your .emacs and now Emacs fails starting up?

Try running Emacs with the option --debug-init to get a full backtrace.

[stardiviner]

No, I mean after added that line into my .emacs, I can run Emacs, but my alias alias e=emacsclient -c will fail at first time when I open a file e filename.sh, and shows that error message in shell, but the second time I can open the file successfully without any error. This is where I find it weird.

(Sorry I have not declare my situation clearly at first)

And even I turn the debug option on, I still get same error output. No backtrace for the emacsclient opening file.

[nonsequitur]

1. Does the same error occur when you open the file by find-file right after starting Emacs?
2. Could you check if the error persists if you run your config in Emacs 24 instead of 25?

[stardiviner]

1. Never have error when I use find-file
2. I'm using Arch Linux, I need to google it how to install Emacs 24 on Arch. (I will update later)

It's probably related to symlinks. Here's the relevant issue.
