I installed ubuntu 12.04 64-bit I have python 2.7 with some additional packages. When I try to use simple command in python like for example
help('modules') I have an error and python terminates.
>>> 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:2729): 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)
In addition I cannot install matplotlib. In a long error log, apart of other stuff I have:

I tried to install gtk from synaptic but did not find exact match for gtk and installed libraries with its dependencies which I thought are the closest. I am not sure how to test if I have it correctly installed and how to fix my python's problem
