Testcase for MRO error (1.57 KB, text/x-python)
2009-07-09 05:03 UTC, Ángel Guzmán Maeso (shakaran) 		Details

Description Ángel Guzmán Maeso (shakaran) 2009-07-09 05:01:34 UTC 
Steps to reproduce:
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:
$ python
Python 2.6.2+ (release26-maint, Jun 19 2009, 15:14:35)
[GCC 4.4.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gtk
>>> b = gtk.VolumeButton()
>>> b.get_popup().get_child().get_child().get_children()[1]
<gtk.ScaleButtonScale object at 0x853e43c (GtkScaleButtonScale at 0x85fb030)>

I thing that the problem is some property object hidden or similar.
