In protected_menu_item_descriptor_to_widget_value (menubar-x.c), we
explicitly pass the UNINHIBIT_QUIT flag.  The comment above that
function says that we "need to reenable quit checking, which was
disabled by next_event_internal() so as to read C-g as an event".
However, when we do read C-g as an event, we get this crash.  I don't
see a way to fix this without immediately undoing all this work to
inhibit QUIT again.  So the radical solution to this problem is to
change that flag to INHIBIT_QUIT, which means C-g will not break you
out of a menu browse gone bad.  I don't see a less radical solution
right now, although I'll think on it some more.
