Thanks to all who replied with comments.
Here is the working function:
void build_server_list (GtkWidget *treeview)
{
GtkListStore *liststore;
GtkTreeIter iter;
GtkCellRenderer *text_renderer = gtk_cell_renderer_text_new();
GtkCellRenderer *pixbuf_renderer = gtk_cell_renderer_pixbuf_new();
GdkPixbuf *ws_pixbuf, *sv_pixbuf, *hp_pixbuf;
GtkTreeViewColumn *pixbuf_column, *text_column;
gint i = 0;
gint count = 0;
/* CREATE THE LISTSTORE MODEL */
liststore = gtk_list_store_new(2, GDK_TYPE_PIXBUF, G_TYPE_STRING);
/* ATTACHED THE LISTSTORE MODEL TO THE TREEVIEW */
gtk_tree_view_set_model(GTK_TREE_VIEW(treeview),
GTK_TREE_MODEL(liststore));
/* DESCRIBE EACH COLUMN */
pixbuf_column = gtk_tree_view_column_new_with_attributes (
"Icon",
pixbuf_renderer,
"pixbuf", 0,
NULL);
gtk_tree_view_append_column (GTK_TREE_VIEW(treeview), pixbuf_column);
text_column = gtk_tree_view_column_new_with_attributes (
"Machine",
text_renderer,
"text", 1,
NULL);
gtk_tree_view_append_column (GTK_TREE_VIEW(treeview), text_column);
/* GET SOME STOCK ICONS */
/* getting a 'pixbuf' icon is the key here */
ws_pixbuf = gtk_widget_render_icon(treeview, GTK_STOCK_ABOUT,
GTK_ICON_SIZE_SMALL_TOOLBAR, NULL);
sv_pixbuf = gtk_widget_render_icon(treeview, GTK_STOCK_HARDDISK,
GTK_ICON_SIZE_SMALL_TOOLBAR, NULL);
hp_pixbuf = gtk_widget_render_icon(treeview, GTK_STOCK_NETWORK,
GTK_ICON_SIZE_SMALL_TOOLBAR, NULL);
/* FILL LISTSTORE MODEL WITH DATA */
/* workstations */
count = g_strv_length(workstations);
for (i=0; i<count; i++) {
gtk_list_store_append(liststore, &iter);
gtk_list_store_set(liststore, &iter,
0, ws_pixbuf,
1, workstations[i],
-1);
}
/* linux servers */
count = g_strv_length(servers_linux);
for (i=0; i<count; i++) {
gtk_list_store_append(liststore, &iter);
gtk_list_store_set(liststore, &iter,
0, sv_pixbuf,
1, servers_linux[i],
-1);
}
/* hp servers */
count = g_strv_length(servers_hp);

gtk_list_store_append(liststore, &iter);

}
