You can't currently remove list nodes inside a foreach. In GLib 2.0,
this works though.

The function changed as follows:

1.2:

void
g_slist_foreach (GSList   *list,
                 GFunc     func,
                 gpointer  user_data)
{
  while (list)
    {
      (*func) (list->data, user_data);
      list = list->next;
    }
}

2.0:

void
g_slist_foreach (GSList   *list,
                 GFunc     func,
                 gpointer  user_data)
{
  while (list)
    {
      GSList *next = list->next;
      (*func) (list->data, user_data);
      list = next;
    }
}

So you see the issue in 1.2 with removing the node you're currently on.
