Hmm, sort of looks like the underlying cppu stuff, or something it uses,
got pulled out from under it during the test. I don't think it could
have gotten that far for the uno::sequence dtor (which looks up the type
of its argument) to blow up without the type system working earlier.

So maybe some other build process is modifying the shared .rdb files,
poking at the testtools bridge test which noone ever complains about and
which is run every time I see it simply copies the .rdb locally, so that
might be worth a shot as an experiment, so pushed that for a test now.
