bug#7361: 23.2; python-describe-symbol fails

Hello!

python-describe-symbol fails for me, i.e. on the following minimal
example (| shows cursor pos):

import os.path
os.path.abspath|

Instead of description of abspath, C-c C-f shows a backtrace:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/share/emacs/23.2/etc/emacs2.py", line 202, in ehelp

  File "/usr/lib/python2.6/site.py", line 432, in __call__
    return pydoc.help(*args, **kwds)
  File "/usr/lib/python2.6/pydoc.py", line 1730, in __call__
    self.help(request)

    if not sys.stdin.isatty() or not sys.stdout.isatty():

Not reproducible with emacs -Q, but I don't see how my customizations
could interfere:

Thanks for the report; sorry no-one ever replied.

If you still see this issue with the latest Emacs, please try and narrow
down which customization causes it. Eg comment out half of them, see if
it still occurs, repeat.

Following is the only one that seems obviously python related.

Cannot reproduce anymore on GNU Emacs 23.4.1 (i486-pc-linux-gnu, GTK+
Version 2.24.10). Should have been fixed somehow.

Best wishes,
