Details:
In wml_menu_item::update(const vconfig & vcfg) there should be references.
Here's the fiff:

However, I still get a crash similar to this trace once a scenario attempts to
autosave at start:

It happens at the show_if_.get_config()/filter_location_.get_config() calls in
wml_menu_item::to_config(config & cfg) const because those members contain
garbage at that point. They are still correct in wml_menu_item::update(const
vconfig & vcfg) (and I don't find out now why is that, perhaps
wml_menu_item::operator= should be defined ?)
Here's some reproduction wml. Don't have other menu items in there.
