warning when importing graph_tool.all

Hi, all

I install graph tool and when I passed the following command I am having the
above warning message, what is that? I am using ipython

In [1]: 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

Cheers

This is just a harmless warning emitted by the gobject bindings (not
part of graph-tool). You can safely ignore it. However, if it annoys
you, you should submit a bug to the gnome/gtk developers.

Cheers,
