g_signal_emit_by_name

[Thym <thymus gmail com>]

Good evening everybody !

I speak french, so sorry for mistakes :]

I think I have matter with g_signal_emit_by_name.

I sent a signal with : 

g_signal_emit_by_name(G_OBJECT(pMyApp->pWindow), "delete_event");

Before, I connected this signal with : 

g_signal_connect(G_OBJECT(pMyApp->pWindow), "delete_event", 
G_CALLBACK(delete_event), (gpointer)pMyApp);

My function delete_event is :

static gboolean delete_event(GtkWidget *pWidget, GdkEvent *event, gpointer 
pdata) {

MainWindow *pMyApp;
GtkWidget *pQuestion;
gboolean bRetour;

pMyApp = (MainWindow *)pdata;

if ( pMyApp->is_menu_edited ) {
pQuestion = gtk_message_dialog_new(GTK_WINDOW(pMyApp->pWindow), 
GTK_DIALOG_MODAL, GTK_MESSAGE_QUESTION, GTK_BUTTONS_YES_NO,
"\nEtes-vous sûr de vouloir\nquitter sans enregistrer ?");
gtk_window_set_title(GTK_WINDOW(pQuestion), "Quitter ?");

switch ( gtk_dialog_run(GTK_DIALOG(pQuestion)) ) {
case GTK_RESPONSE_YES:
bRetour = FALSE;
break;
case GTK_RESPONSE_NO:
bRetour = TRUE;
}

gtk_widget_destroy(pQuestion);

return bRetour;
}
else
return FALSE;
}

If I closed the window with the window manager, all's right.

But, if I send "delete_event", the function delete_event is right called, 
but I have an error after :

(gdb) run
Starting program: /home/thymus/svn/fb-menu-editor/obj/fb-menu-editor 

Program received signal SIGSEGV, Segmentation fault.
0xb7b4c823 in g_pointer_type_register_static () from 
/usr/X11R6/lib/libgobject-2.0.so.0

I don't understand why...

Thank you :]
