Erm. That might be me... sorry about that :-) Got my eastings and northings
mixed up whilst getting map projections working in josm. I patched it up
pretty quickly but the planet dump seems to have caught it.

For anyone who cares, I moved some nodes very slightly, then wrote them back
with lat/long instead of long/lat. Thus, some segments going from (-0.2, 51)
to (51, -0.2) or something.

Getting eastings and northings the right way for arbitrary projections is
actually a bit of a pain...
