Unable to load stock icons

[Thomas Dybdahl Ahle <lobais gmail com>]

Hey, I'm writing an app, using pygtk, looking up icons using
gtk.icon_theme_get_default().load_icon(...).

Now I've got reports from some KDE users which are unable to load even
tango specified icons this way. Also when the gnome-icon-theme is
installed and the icons are easily found in /usr/share/icons/gnome.

I've made sure that the XDG_DATA_DIRS variable was set correct.

I wonder how gtk.icon_theme_get_default().load_icon(...) works. How does
it know where to look up icons?

If there isn't a way to configure gtk to make it find the stock-icons,
do you think it would be possible to fall back on loading icons with
gtk.gdk.pixbuf_new_from_file on the /usr/share/icons/gnome folder?

The report I got was this:

Thanks,
