Setting an empty ListStore as TreeView's model causes crash when headers are visible

PS: In my real code, calling store.clear() after initialization helps as well, still no idea why it doesn't work in this toy example.

I think the problem lies below: directly in C libraries. Might be worth opening them an issue as well.

This functionality seems so basic and common that I was assuming it's not GTK problem, but you're right, I gonna check it tomorrow.

Thanks! I really hope the problem is coming from gtk-rs but I'm afraid it's not... Waiting to hear back from you!

@GuillaumeGomez You're right, this is GTK problem. C version:

#include <gtk/gtk.h>

enum { COL_NAME = 0, COL_AGE, NUM_COLS };

static GtkTreeModel *create_and_fill_model(void) {
    GtkListStore *store;
    store = gtk_list_store_new(NUM_COLS, G_TYPE_STRING, G_TYPE_UINT);
    // Uncommenting these fixes the issue:
    // GtkTreeIter iter;
    // gtk_list_store_append(store, &iter);
    // gtk_list_store_set(store, &iter, COL_NAME, "Heinz", COL_AGE, 51, -1);
    return GTK_TREE_MODEL(store);
}

static GtkWidget *create_view_and_model(void) {
    GtkCellRenderer *renderer;
    GtkTreeModel *model;
    GtkWidget *view;
    view = gtk_tree_view_new();
    renderer = gtk_cell_renderer_text_new();
    gtk_tree_view_insert_column_with_attributes(
        GTK_TREE_VIEW(view), -1, "Name", renderer, "text", COL_NAME, NULL);
    renderer = gtk_cell_renderer_text_new();
    gtk_tree_view_insert_column_with_attributes(
        GTK_TREE_VIEW(view), -1, "Age", renderer, "text", COL_AGE, NULL);
    model = create_and_fill_model();
    gtk_tree_view_set_model(GTK_TREE_VIEW(view), model);
    g_object_unref(model);
    return view;
}

int main(int argc, char **argv) {
    GtkWidget *window;
    GtkWidget *view;
    gtk_init(&argc, &argv);
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    g_signal_connect(window, "delete_event", gtk_main_quit, NULL);
    view = create_view_and_model();
    gtk_container_add(GTK_CONTAINER(window), view);
    gtk_widget_show_all(window);
    gtk_main();
    return 0;
}

Can you link here the gtk issue when it's open please?
