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
    except: help (name)
  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)
  File "/usr/lib/python2.6/pydoc.py", line 1775, in help
    elif request: doc(request, 'Help on %s:')

    pager(render_doc(thing, title, forceload))
  File "/usr/lib/python2.6/pydoc.py", line 1321, in pager
    pager = getpager()
  File "/usr/lib/python2.6/pydoc.py", line 1328, in getpager
    if not sys.stdin.isatty() or not sys.stdout.isatty():
ValueError: I/O operation on closed file

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