This was interesting. The core problem was that there are two ways to
set the units in a drawing - one with the setUnits() method and the
other by setOption('UNITS', xxx). The trouble various places used
setOption() to do the dirty work, but it didn't go through.

The small patch below fixed things for me. Please apply and let me know
that it works for you as well.

The next challenge is to figure out the other bug you described.
