python fail to display list of modules

I have new installation of ubuntu 12.04 64-bit. I have python 2.7 and installed python 3.3 as python3 up to now did not have problems, but installation is fairly new. When I try to check modules I installed by using help('modules') I have an error:

Python 2.7.3 (default, Aug  1 2012, 05:14:39) 
[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...

/usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
  import gobject._gobject
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
  from gtk import _gtk

** (python:20929): CRITICAL **: pyg_register_boxed: assertion `boxed_type != 0' failed
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: cannot register existing type `GdkDevice'
  from gtk import _gtk
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_get_qdata: assertion `node != NULL' failed
  from gtk import _gtk
Segmentation fault (core dumped)

I have no idea how to interpret this output and what I should do. Obviously if there is some problem I want to fix it now after OS installation and do not wait until will loose a work. Anyone had similar issue and know what should be done?

Use help() function, then enter the "interactive help" interface.

>>> help()

>>> help>

then enter:

>>> help> modules

This way is available.

This seems to be a popular bug of python on newer ubuntu versions. It has to do with the mixing of modules which have different bindings, see here:

I also have this problem and some suggestions how to solve it can be found here:
