[Bug 896836] Re: Segmentation fault when asking help() for the list of modules

[Hardik Sanchawat (OpenERP)]

Ubuntu 12.10

 am facing following traceback  while using command for displaying list
of modules of python.

~$ python
Python 2.7.3 (default, Sep 26 2013, 20:08:41) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> help('modules')

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

matplotlib must be installed in order to use SimplePlot!
An error occured setting up the themes: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

Bug description:
  Using Python 2.7.2 on Oneiric (package version is 2.7.2-7ubuntu2), I'm
  getting a consistent segmentation fault when I open the interactive
  help in a Python shell (i.e. typing "help()" in the shell) and then
  ask for the list of modules (by typing "modules").

  The error code returned is as follows:
