I have a feeling that we've changed some things to work with newer
versions of plt scheme which crash in older versions. It may be a
coincident, but Kassen found a bug that caused crashes in version 4.2.4
which I reported and fixed locally in my PLT source, perhaps these
versions have similar problems.

Right, I need to downgrade plt to this version and see if that's the
problem.
