Yeah, that's 744717. The bug isn't incredibly clear and I didn't do a very good job of summarizing it. If you look at the before and after grub.cfg files, you can see it though.
How often would that happen in a guest? I don't think that I have submenu entries in any of my DomUs.
I don't think it is particularly likely to happen unless submenus are used for something else. Someone might install a xen hypervisor on a guest by mistake, but it isn't that likely. I did it deliberately for grub2 testing as I am still on grub1 on my base system.
