This can be closed, it works now and it seems fixed on Ubuntu 12.10
(maybe it was fixed before).

Title:
gtk.VolumeButton() throws a error (MRO) for bases ImplementorIface on
Karmic
Status in PyGTK: GTK+ for Python:
Invalid
Status in “pygtk” package in Ubuntu:
Triaged
Bug description:
I recently planned an application where I want to customize the widget
gtk.VolumeButton(). My intention is to change the appearance of more
and less buttons icons and change the subject inside
gtk.ScaleButton(). But to my surprise I receive an error MRO:
TypeError: Cannot create a consistent method resolution
order (MRO) for bases ImplementorIface, Buildable, gtk.Orientable
ERROR:/build/buildd/pygobject-2.18.0/gobject/pygobject.c:924:pygobject_new_full:
assertion failed: (tp != NULL)
/usr/bin/tivion: line 5: 30042 Cancelado python
tivion.py $1 $2 $3 $4
I attached a completed test case.
By the other hand, if you put this code in a python console, you dont get any
error:

I thing that the problem is some property object hidden or similar.
The bug 279579 seems to be similar, but this is other code with
another property.
