Tony,
I don't claim to be an expert but I have used IconViews & TreeViews. I
have never seen it attempted the way you show. Using GDK_TYPE_PIXBUF as
the column type is all I have every tried, based on code I've seen from
others, and it has always worked.
Here are a few observation of your code.
1. I have been successful using the following creation order.
A. Load all icons I plan to use into an array of *pixbuf or some
type of permanent(life of the app) container.
B. Create the list store
model = GTK_TREE_MODEL (gtk_list_store_new (2,
GDK_TYPE_PIXBUF, /* ICON
*/
G_TYPE_STRING /*
Location Name */
));
C. Create the iconview (or treeview) & show it, plan on adding it to
a scrolled_window.
iconview = gtk_icon_view_new_with_model (GTK_TREE_MODEL (model));
gtk_icon_view_set_orientation (GTK_ICON_VIEW (iconview),
GTK_ORIENTATION_VERTICAL);
gtk_icon_view_set_columns (GTK_ICON_VIEW (iconview), -1);
gtk_icon_view_set_selection_mode (GTK_ICON_VIEW (iconview),
GTK_SELECTION_SINGLE);
gtk_icon_view_set_pixbuf_column (GTK_ICON_VIEW (iconview),
ID_SEL_ICON);
gtk_icon_view_set_markup_column (GTK_ICON_VIEW (iconview),
ID_SEL_LABEL);
D. Load each record to the list store with a pointer to pixmap, and
text string
gtk_list_store_prepend (GTK_LIST_STORE (model), &iter);
gtk_list_store_set (GTK_LIST_STORE (model), &iter,
ID_SEL_ICON, pixbuf, ID_SEL_LABEL, "Home", -1);
Iconviews don't need all the renderer fuss and may work well for you.
gfhcm.sourceforge.net contains an application i wrote that uses both
icon views and tree views, look at the gfhcm-client or gfhcmc codeset.
You might also find answers for the GTK API Docs or the TreeView
tutorial.

Hope this helps,
