Bug#618557: gi.repository's Gtk.Window() fails with gtk3

[chrysn]

Package: python-gobject
Version: 2.27.0-2
Severity: normal
Tags: experimental

when trying to create a gtk window using gtk3, i get the following:

>>> from gi.repository import Gtk
>>> w = Gtk.Window()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/pymodules/python2.6/gtk-2.0/gi/module.py", line 234, in __getattr__
    self._import()
  File "/usr/lib/pymodules/python2.6/gtk-2.0/gi/module.py", line 228, in _import
    overrides_modules = __import__('gi.overrides', fromlist=[self._namespace])
  File "/usr/lib/pymodules/python2.6/gtk-2.0/gi/overrides/Gtk.py", line 60, in <module>
    class Editable(Gtk.Editable):
  File "/usr/lib/pymodules/python2.6/gtk-2.0/gi/types.py", line 139, in __init__
    cls._setup_vfuncs()
  File "/usr/lib/pymodules/python2.6/gtk-2.0/gi/types.py", line 107, in _setup_vfuncs
    vfunc_info.get_name()))
TypeError: Class implementing Gtk.Editable should implement the method do_changed()

i have gir1.2-gtk-3.0 installed in version 3.0.2-1. everything works
well with gir1.2-gtk-2.0. it seems to me that pygobject mixes up gtk3
stuff (without any gir1.2-gtk installed, not even the Gtk import works)
with gtk2 stuff (the /gtk-2.0/ part in the backtrace's paths).

at [1] it was pointed out that i could "just comment [the exception in
line 107] out and the overrides should load" -- that indeed makes it
work, i'm just not familiar enough with gtk3 to say how completely it
works, and there is probably a deeper reason to that exception.

i hope the information below is complete; i created this bug report from
a schroot as i have software installed that conflicts with gir1.2 on my
main system.
