Some gtk apps not starting up

[Madhurya Kakati <mkakati2805@xxxxxxxxx>]

Hi,
I recently installed and then uninstalled gnome 3
(gnome-unstable/gnome gnome-unstable/gnome-extra). Now whenever I try
to start some gtk app I get some error regaring python.
Here are 2 examples:

blueman-applet

[papul@papuldesktop ~]$ blueman-applet
Traceback (most recent call last):
  File "/usr/bin/blueman-applet", line 26, in <module>
    import pynotify
  File "/usr/lib/python2.7/site-packages/gtk-2.0/pynotify/__init__.py",
line 19, in <module>
    import gtk
  File "/usr/lib/python2.7/site-packages/gtk-2.0/gtk/__init__.py",
line 40, in <module>
    from gtk import _gtk
ImportError: /usr/lib/python2.7/site-packages/gtk-2.0/gtk/_gtk.so:
undefined symbol: gtk_combo_box_set_entry_text_column


Sonata

[papul@papuldesktop ~]$ sonata
Traceback (most recent call last):
  File "/usr/bin/sonata", line 126, in <module>
    import gtk
  File "/usr/lib/python2.7/site-packages/gtk-2.0/gtk/__init__.py",
line 40, in <module>
    from gtk import _gtk
ImportError: /usr/lib/python2.7/site-packages/gtk-2.0/gtk/_gtk.so:
undefined symbol: gtk_combo_box_set_entry_text_column

Please tell me whats wrong and how do i solve this problem?
Thanks.
