GtkTreeStore doesn't handle GtkBuildable <data> tag.

[Luca Livraghi]

Binary package hint: glade-3

Hi, I'm on Ubuntu 9.04 and I'm testing the new Glade 3.6 using python. When I implement a treeview widget using gtk.Builder(), I get a message: glib.GError: Unhandled tag: 'data'
I tried to investigate on this, and I discovered that in the glade file there a part that is currently having problems. It's the code inside the <data></data> tag.
You can reproduce this bug just by extracting the tar archive I attached and typing on the terminal python Gui.py

Thanks for your bug report. I'm reassigning to GTK+ as Glade 3.6 is able to load this UI file correctly - It is when loading in GTK+ where the problem occurs.

The problem appears to be in:
gtk/gtktreestore.c: gtk_tree_store_buildable_custom_tag_start()
Where it doesn't handle the <data> tag.

Compare to:
gtk/gtkliststore.c: gtk_list_store_buildable_custom_tag_start()
Which does handle this tag (it ignores it).

Upstream bug created:
http://bugzilla.gnome.org/show_bug.cgi?id=577685

GTK+ does not currently support setting data for treestores. As a workaround remove all data for any treestores (by hand or in Glade) until this feature is supported.

Upstream has confirmed this is a bug in Glade 3 (the data for TreeStore GtkBuildable has yet to be defined). This feature will be removed in Glade 3.6.1.

Fixed in Glade 3.6.2 (by removing support for treestore data)
