Thanks for the small example. This should now be fixed. Your first
example now spaces on 5 pages (3 on the first, 4 on the rest). Your
minimal example now uses 3 pages (with a single system on the last
page). If you set ragged-bottom-last to #f, however (which is generally
a better setting with the new page breakers), it only takes up 2 pages.

For what it's worth, the problem was with the height-estimation of
Hara-kiri staves. You can see the problem by looking at the
annotated-spacing: the Y-extent-estimate intervals on some of the staves
are way too big.

Cheers,
Joe
