memory leaking with gtk_menu_new

[Allin Cottrell <cottrell wfu edu>]

In checking my app with memprof I'm seeing a memory leak of 176 bytes 
whenever I close a window which has an associated popup menu.

Can anyone tell me what I'm doing wrong?

I'm creating the menu with

GtkWidget *popup = gtk_menu_new();

and adding items with

GtkWidget *item;
item = gtk_menu_item_new_with_label("whatever");
gtk_menu_shell_append(GTK_MENU_SHELL(popup), item);

Then when the "parent" window is closed, I'm doing

gtk_widget_destroy(popup);

I put in some printfs to verify that the "destroy" is being performed, 
and on the same address returned by the initial gtk_menu_new().

Memprof gives this trace:
