Bug Description

I get the following error when trying to execute a buffer

Debugger entered--Lisp error: (invalid-regexp "Trailing backslash")
  string-match("\\" "ipython")
  (if (string-match sepchar name) (progn (setq prefix "ND")))
  (when (string-match sepchar name) (setq prefix "ND"))
  (let ((sepchar (or sepchar (py-separator-char))) prefix erg suffix) (when (string-match sepchar name) (setq prefix "ND")) (setq erg (cond ((string-match "ipython" name) (replace-regexp-in-string "ipython" "IPython" name)) ((string-match "jython" name) (replace-regexp-in-string "jython" "Jython" name)) ((string-match "python" name) (replace-regexp-in-string "python" "Python" name)) (t name))) (when dedicated (setq erg (make-temp-name (concat erg "-")))) (cond ((and prefix (string-match "^*" erg)) (setq erg (replace-regexp-in-string "^*" (concat "*" prefix " ") erg))) (prefix (setq erg (concat "*" prefix " " erg "*"))) (t (setq erg (concat "*" erg "*")))) erg)
  py-buffer-name-prepare("ipython" "\\")

I am on Mac OS X 10.6.8 using emacs 24.0.95.1. py-shell-name is set to "ipython".

What version are you using? With r930 I get rather similar behavior on my Mac when I visit a buffer, but it goes away if I put the line

(setq py-separator-char 47)

in my init.el.

that meets it here:

running into trouble with tests from batch,
same tests pass when started interactively...

I'll push some changes - not solved yet

Forgot to report back. (setq py-separator-char 47) works indeed. I think it should be documented somewhere though.

Even easier would be to make this the default setting inside python-mode.
