Invalid type argument: number-or-marker-p

What Emacs is complaining about. This error happens to me every once in a while, but I'm new to the Emacs world and not so expert in C. Now emacs stops me there and doesn’t even let me open the brackets to save the encoding? What does this error mean?

emacs error

EDIT : My version of Emacs:

emacs version
