Getting crazy with GtkCTree widget

[José Carlos García Sogo <jsogo arrakis es>]

 First of all hello! I'm new to this list.

 Well, I'm writing a GTK/GNOME application called Seahorse
(http://seahorse.sourceforge.net), and for the keymanager I'm using a
CTree widget. I can build the CTree without any problem, but things
change when I want to access data in it.

 When a user clicks on a button, I get the slected node through this
function:

GtkCTreeNode*
keymanager_get_selected_node (void)
{
        GtkCTreeNode* node = NULL;
        GList* list;
        
        list = GTK_CLIST(keylist)->selection;
        if (list != NULL)
                node = GTK_CTREE_NODE(list->data);

        return node;
}

  This function returns me the node ok. Then I want, for example, get
the data stored in first column of the row. So I call this other
function:
gchar *
keymanager_get_username_from_node (GtkCTreeNode* node)
{
   gchar **data;
                   
   if (node != NULL)
        gtk_ctree_get_node_info (GTK_CTREE(keylist), node, data,
NULL,NULL,NULL,NULL,NULL,NULL,NULL);

   return data[0];
}

 Here starts the problems: this functions only gives me the first column
(which I want here, but no in other functions), and garbage in the
others. To solve this I need to use gtk_ctree_node_get_text to retrieve
data stored in other columns (but not in the first one! If I try with
this function it crahses!)

 Well. Once I have "solved" this little problem with this hack. The REAL
problem appears. Let's see this function:
void
on_signkey_ok_clicked                 (GtkButton       *button,
                                        gpointer         user_data)
{
        [vars declaration]      


                [some stuff here]

        node = keymanager_get_selected_node ();
        type = keymanager_get_type_from_node (node);
        
        if (type == 2) {
                uidname = g_strdup (keymanager_get_username_from_node (node));
                
                keyid = g_strdup (keymanager_get_keyid_from_node (node));
                key = keyring_get_key_with_keyid (MyKeyring, keyid);
                
                uid_nr = keyring_get_key_uid_position_with_userid (key, uidname);
                free (uidname);
        }
        else    keyid = g_strdup (keymanager_get_keyid_from_node (node));
        
                [more stuff here]       
         
        gtk_widget_destroy (GTK_WIDGET(dialog));
        
        display_keyring (keylist);
        
        free (keyid);
}

 As you can see I get the node, and type through two first functions.
This works.
 If type == 2 I get uidname which also works, but when I try to get
keyid the program crash with a funny SIGSEGV, but if type != 2 I get
keyid properly.

 So I don't know where's the problem. I'm getting crazy!

 If anyone could help me I'll be very pleased. 

  Thank you!
