Re: Would this leak be inside gtk?

[Edscott Wilson <edscott wilson garcia gmail com>]

I conclude this is a gtk memory leak. It occurs when calling
gtk_combo_box_new_with_entry(), Apparently, when the dialog that contains
the combo box is destroyed, the GList "visible_children" in file
gtkcombobox.c is not being cleansed of the pointer to the child widget,
entry. The leak does not occur if plain gtk_combo_box_new() is used
instead. Correct me if I'm wrong.

Here's a valgrind suppression entry:
{
   libgtk:comboboxwithentry
   Memcheck:Leak
   fun:malloc
   fun:g_malloc
   fun:g_slice_alloc
   fun:g_list_prepend
   fun:gtk_combo_box_get_path_for_child
   fun:gtk_widget_get_path
   fun:reset_style_recurse
   fun:gtk_widget_set_parent
   fun:gtk_combo_box_add
   fun:g_closure_invoke
}
