Thanks for the test case.
The test seems to work fine on 0.95. And on FOP Trunk I don't see a
deadlock but an infinite loop in PageBreakingAlgorithm (related to
footnote handling).
I don't have time right now to dive deeper into this but the following
patch at least breaks the infinite loop. But I haven't tested the
semantics to see if I broke anything. So you may want to use FOP 0.95
for the moment. We need to take a closer look at this problem.
