PyGtk applications crash with ImportError: /usr/lib/python2.7/dist-packages/gtk-2.0/gtk/_gtk.so: undefined symbol: gtk_item_factory_get_widget_by_action

[vden]

Every PyGtk application that I've tried to run started crashing after the last update with exception like this:
Traceback (most recent call last):
  File "/usr/bin/sonata", line 126, in <module>
    import gtk
  File "/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py", line 40, in <module>
    from gtk import _gtk
ImportError: /usr/lib/python2.7/dist-packages/gtk-2.0/gtk/_gtk.so: undefined symbol: gtk_item_factory_get_widget_by_action

ImportError is the same for all of them.

I checked sonata, indicator-weather, indicator-workspaces and so on and no one works for me. Regular gtk2 applications work well.

Thank you for your bug report, could you run "ldd /usr/lib/python2.7/dist-packages/gtk-2.0/gtk/_gtk.so" and add that to the bug? The issue is likely a /usr/local/something installation

And even more weird:

$ nm -D /usr/lib/python2.7/dist-packages/gtk-2.0/gtk/_gtk.so | grep gtk_item_factory_get_widget_by_action
                 U gtk_item_factory_get_widget_by_action

[Sebastien Bacher (seb128)]

can you try to strace python ... and see what files are opened?

[vden (denis-voskvitsov)]

After reinstalling meta-package libgtk2.0 the bug was magically resolved.
Anyway, thank you for your support, Sebastien.

[vden (denis-voskvitsov)]

Fixed by reinstalling libgtk2.0.
