tab-completion in sage_mode / emacs broken

[Martin R]

Hi there,

I just installed sage 6.3.beta1 (via git) and sage_mode.

Unfortunately, tab completion is broken in emacs.

I'm using GNU Emacs 23.3.1 (x86_64-pc-linux-gnu, GTK+ Version 2.24.10).

When I press tab, the mouse pointer changes into the "please wait"
thingy, and nothing happens.  top doesn't show any activity.  I tried
edebug on

(defun sage-pcomplete-or-help ()
  "If point is after ?, describe preceding symbol; otherwise, pcomplete."
  (interactive)
  (if (not (looking-back "[^\\?]\\?"))
      (pcomplete)
    (save-excursion
      (backward-char)
      (when (python-current-word)
    (ipython-describe-symbol (python-current-word))))))

But I don't know where to go from here. (Of course, pcomplete is not
returning...)

Thanks for any help,

Martin
