python(pdb) & gud: "stop" causes uncaught exception

[David Reitter]

Pressing the "stop" button in gud with pdb running (gud-stop-subjob)  
causes an unhandled python exception (stack trace below).

Emacs then pops up cmd.py on line 151, near "except ImportError",  
which is at the end of the following:

        finally:
            if self.use_rawinput and self.completekey:
                try:
                    import readline
                    readline.set_completer(self.old_completer)
                except ImportError:
                    pass

I've got Python 2.4.1 installed, and the `python.el' from the GNU  
Emacs CVS (the one which was just taken out / put back in?) is in use.
