Title:
  pydoc / python help mode crashes importing incompatible extensions

Status in “python-defaults” package in Ubuntu:
  Expired

Bug description:
  I am a beginner on python and I tried to get help from python modules
  when suddenly I receive warning as below :

  $python
  Python 2.7.3 (default, Apr 20 2012, 22:44:07) 
  [GCC 4.6.3] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  >>> help ()

  Welcome to Python 2.7!  This is the online help utility.

  If this is your first time using Python, you should definitely check out
  the tutorial on the Internet at http://docs.python.org/tutorial/.

  Enter the name of any module, keyword, or topic to get help on writing
  Python programs and using Python modules.  To quit this help utility and
  return to the interpreter, just type "quit".

  To get a list of available modules, keywords, or topics, type "modules",
  "keywords", or "topics".  Each module also comes with a one-line summary
  of what it does; to list the modules whose summaries contain a given word
  such as "spam", type "modules spam".

  help> modules

  Please wait a moment while I gather a list of all available modules...
