Re: GTKTreeView Question. (COre Dump on GList append)

[Harring Figueiredo <harringf yahoo com>]

 Thanks David,

 I tried to do like the API suggests. 
 I am getting a core dum on the fillowing code.

 gdb output:

Program received signal SIGSEGV, Segmentation fault.
0x403f03ba in g_list_last (list=0x7) at glist.c:628
628             list = list->next;
(gdb) where
#0  0x403f03ba in g_list_last (list=0x7) at glist.c:628
#1  0x403efc81 in g_list_append (list=0x8187668, data=0x7) at glist.c:250
#2  0x0804e42a in remove_input_dir_from_treeview (button=0x8187668, empty=0x0)
    at settings_ui.c:34


  Here is the source code.
     30     for(tmpl = list; tmpl != NULL; tmpl = tmpl->next) {
     31         GtkTreeRowReference* ref =
     32             gtk_tree_row_reference_new (model, tmpl->data);
     33         if(ref)
     34             refs = g_list_append(refs,ref);
     35         g_warning("Ref!!!\n");
     36     }

  refs --> GList* (Initially null)
  
  list ->  GList returned from " list = gtk_tree_selection_get_selected_rows
(selection, &model);"


   I can not figure out the reason why this is happening.

   Any suggestion ?

Harring.
