py-help-at-point doesn't work any longer

[Theller-users]

C-c C-h py-help-at-point gives 'Selecting deleted or
non-existant buffer'.

This problem only occurrs when there is no *Python* shell
buffer. Hitting C-c ! makes the problem disappear.

Thanks. I started working on this last night and think I
have a fix.

Worrying that fixing this problem in the obvious way might
lead to
other problems elsewhere leads me to wonder if there's a
unit test
package for Emacs Lisp that's similar to Python's unittest
module.

I have no idea, but I'm quite sure you will get usefull
answers on the (x)emacs mailing lists.
