Indeed, I can reproduce this in Emacs-24.3.91.  The important detail is
not to hit "," but to insert a char right before the inner close paren.

The problem seems to be in python-indent-post-self-insert-function,
where the "still in parenthesis" check doesn't realize that it's within
a different pair of parens.

Looks like it, yes.  Fabián, can you take care of it?

A temporary workaround could be

(add-hook 'python-mode-hook
          (lambda ()
            (remove-hook 'post-self-insert-hook
                         #'python-indent-post-self-insert-function 'local)))
