Public bug reported: This should not be happening at all. Install fails with a grub-install error; failing to find /dev/dm-0. Interestingly, I picked "Erase entire disk", for a system (Dell Vostro V130) that was previously installed with Xubuntu. Given that "Erase entire disk" should just wipe all partitions and create new ones, none of which using LVM (because that was not picked at all, neither LVM not LVM with crypto); it should not be trying to use dm-0 at all.
There are other errors earlier on with ubiquity failing to properly recognize the type of filesystem.
