Ok, so something in your .emacs is causing this.
Try bisecting it.  Remove half of your .emacs and try again.  If it works, put back the other half, and remove half of that.  If it doesn't work, remove half again, and so on.
Hopefully you can pinpoint what package or lisp statement that causes this.

You can also start Emacs normally and see what the value for before-save-hook is (C-h v before-save-hook).  If it is non-nil, that is a prime suspect.  Try setting it to nil and see if it works.
