Dear Matthias,
Below is a simple program where gtk_combo_box_get_active_text
creates a segfault, as well as my (hacking) way of mending it.
Two other persons from gtk-app-devel-list@gnome.org compiled
it and got no segfault while running. So I rebuilt my system ??
With
pango 1.8.1 in /opt/gnome/share/pango-1.8.1/
atk 1.9.0 in /opt/gnome/share/atk-1.9.0/
gtk+ 2.6.7 in /opt/gnome/share/gtk+-2.6.7/
in this order, all three via
make uninstall
./configure -prefix=/usr
make
make install
and made things tidy (I hope) by running
ldconfig while in /usr/lib. But same result.
Hope that will help you -- and not overcrowed your mbox :-).
Best, and thanks for your work!
Best,
Amities,
Olivier

-------------Complete and Minimal example------------
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <gtk/gtk.h>
GtkWidget *window, *my_combo_box;
void my_gtk_widget_destroy(GtkWidget *widget)
{
gtk_widget_destroy(widget);
gtk_main_quit();
}
void selecter(GtkComboBox *combo)
{
gchar *name;
if ((name = gtk_combo_box_get_active_text
(GTK_COMBO_BOX(my_combo_box))) == NULL){
printf("What are we doing in here ???");
} else {
printf("Ok %s \n", name);};
}
int main(int argc, char *argv[])
{
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
g_signal_connect(G_OBJECT(window), "destroy",
G_CALLBACK(my_gtk_widget_destroy), NULL);
my_combo_box = gtk_combo_box_new_text();
gtk_combo_box_append_text(GTK_COMBO_BOX(my_combo_box), "Oui");
gtk_combo_box_append_text(GTK_COMBO_BOX(my_combo_box), "Non");
/*gtk_combo_box_set_active(GTK_COMBO_BOX (my_combo_box),0);*/
g_signal_connect (G_OBJECT(my_combo_box), "changed",
G_CALLBACK (selecter), NULL);
gtk_container_add(GTK_CONTAINER(window), my_combo_box);
gtk_widget_show_all(window);
gtk_main();
return 0;
}
/*
gcc -Wall -pedantic essai.c -o essai.o -lm `pkg-config --cflags --libs
gtk+-2.0`
*/
-----------------------------------------------------------
When I select an item, I get a segmentation fault.
I replaced gtk_combo_box_get_active_text with the following
that makes this problem disappear :
-----------------------------------------------------------
gchar *
my_gtk_combo_box_get_active_text (GtkComboBox *combo_box)
{
GtkTreeIter iter;
gchar *text = NULL;
GtkTreeModel* model = gtk_combo_box_get_model(combo_box);
if (gtk_combo_box_get_active_iter (combo_box, &iter))
gtk_tree_model_get (model, &iter, 0, &text, -1);
return text;
}
------------------------------------------------------------
