In case nobody has noticed it, in ubuntu 12.04.3 LTS, when I first
import gtk and then list the modules using help, the segmentation fault
does not occur. I suspect it has to do with the static/dynamic nature
of the module being visible. See the terminal capture below as evidence:

[Bug 896836] Re: Segmentation fault when asking help() for the list of modules
As someone in a prior bug-report discovered that uncommenting line 27 in dist-packages/gobject/constants.py cures the crash. Actually that line makes no sense as a python statement, but just listing the variable name TYPE_INVALID, without assigning any value in constants.py (which the comment there states is defined in gobjectmodule.c) eliminates the crash. This would seem to discredit the theory that simultaneous loading of static and dynamic bindings is to blame. Does the variable NEED to be declared in the python even if it's value is assinge in a .c file in order to work ? I'm not knowledgable about the inner workings of the python language.

[Bug 896836] Re: Segmentation fault when asking help() for the list of modules
The simplest combination of modules I can find that causes the segfault
(presumably due to the mixture of static and dynamic bindings for the
gtk module described above) is:
python -c 'import Onboard; import gtk '
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:42: Warning:
g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
from gtk import _gtk
** (python:7386): CRITICAL **: pyg_register_boxed: assertion `boxed_type != 0'
failed
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:42: Warning: cannot

from gtk import _gtk
zsh: segmentation fault python -c 'import Onboard; import gtk '
After removing the 'onboard' package, pydoc -k will get much further
through the list of packages when searching, but now eventually hangs
for me. strace shows it seems to be a race condition on a futex in atk:

It seems like ack's comment points the finger at the help() function within ipython. Has anyone tried to modify it so it doesn't simultaneously load modules with static and dynamic links to _gtk?

This is regarding bug #896836: 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).

[Bug 896836] Re: Segmentation fault when asking help() for the list of modules
From Googling around, this looks to me quite similar to the problem described here: http://blog.rabbitvcs.org/archives/312 The author points to the cause of a mixture of modules with both static and dynamic gtk bindings being active at the same time. Because `help()` (and pydoc for that matter) iterate over all modules, actually importing them to get at the documentation, I believe that this causes a similar incompatible mixture of 'active' modules to occur.
