from graph_tool.all import * failed

Dear all,

I'm trying to take the first steps on using graph-tool. For this purpose,
I'm following the instructions in the "Quick start using graph-tool".
However, I could not advance to next steps due to the following error:

Python 2.7.2+ (default, Oct 4 2011, 20:06:09)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.

from graph_tool.all import *

/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

When I import graph-tool just typing "import graph-tool", everything seems
ok:
Python 2.7.2+ (default, Oct 4 2011, 20:06:09)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.

import graph_tool

Please, let me know what is possibly going wrong!

Thank you in advance!

The message above is not an error, it is just a warning, so you can
safely ignore it. It is caused by the python bindings to GTK, not
graph-tool anyway...

Cheers,
